Charming Kids' Swimwear: Swimsuits & Trunks

Summer calls for swimwear that can keep up with kids - and keep their skin safe while it does. Whether you are planning a beach vacation, pool party, or backyard splash session, finding the right kids swimsuits means balancing comfort, durability, and sun protection in one package. At Aaria Tees, the swimwear collection features over 120 styles designed with both parents and kids in mind, from classic one-pieces to playful two-piece swim sets and quick-dry trunks.

The collection covers every swimwear type a child could need. Girls can choose from ruffle one-pieces, smocked swim sets, and plaid bow designs, while boys can dive into camo trunks, tractor stripe styles, and watermelon-embroidered options - with UPF-protected swim coverups rounding out the range for both. Browse alongside the full kids clothing collection or check out new arrivals for fresh seasonal styles to pair with any swim look.

Every swimsuit in this collection is made with UPF-protective fabric, a feature that blocks up to 98% of harmful UV rays. Unlike regular swimwear, UPF-rated fabric protects your child's sensitive skin throughout every splash, swim, and sunbathing session - no sunscreen required on covered areas.

What Types of Kids Swimsuits Does Aaria Tees Offer?

Aaria Tees carries four main types of kids swimsuits: girls one-piece swimsuits, kids swim sets, boys swim trunks, and swim coverups - all built with UPF sun-protective fabric and playful graphic designs across the range. Whether you are outfitting a toddler headed to her first pool day or a school-age boy gearing up for a full summer of beach adventures, there is a style here for every child. Each type serves a different purpose and suits different ages, activity levels, and preferences, so understanding the differences makes choosing easier.

Girls One-Piece Swimsuits

Girls one-piece swimsuits are the most popular choice for younger children and active swimmers because they stay put, offer full coverage, and are easy to move in. At Aaria Tees, one-pieces come in a range of eye-catching designs that make getting dressed feel like part of the fun. The Blue Flag Applique Gingham Ruffle One-Piece Swimsuit combines vintage-inspired ruffles with a classic gingham pattern and UPF protection, while the Pink Plaid Bow UPF Swim One-Piece delivers a timeless look with a playful bow detail that little girls love. For something bold and nature-inspired, the Camo Mallard Embroidered UPF Swim One-Piece features detailed mallard duck embroidery on a camo base - a style that stands out at any poolside. All one-pieces are crafted from a UPF-rated polyester and spandex blend that offers stretch for active play while blocking harmful UV rays throughout the day.

Key features of Aaria Tees girls one-piece swimsuits:

• UPF-protective fabric built into every style
• Smocked and ruffle detailing for a flattering, comfortable fit
• Designs including gingham, plaid, camo, and watermelon prints
• Priced from $15.99 to $20.99

Kids Swim Sets (Two-Piece)

Kids swim sets offer the flexibility of a top and bottom that move independently, making them a favorite for toddlers who need frequent bathroom breaks and older kids who want to mix and match styles. Aaria Tees' two-piece swim sets are designed with coordinating prints so the whole look stays intentional. The Red Watermelon Smocked UPF Swim Set is a standout - its smocked bodice creates a flattering silhouette while a vibrant watermelon print makes it instantly recognizable on a crowded beach. The Blue Beach Smocked UPF Swim Set pairs structured smocking with a classic coastal color for a timeless look, while the Hot Pink Umbrella Embroidered UPF Swim Set brings bold color and playful embroidery together in one vibrant package. All swim sets feature UPF50+ fabric that blocks 98% of UV rays, so kids stay protected whether they are swimming laps or building sandcastles.

Boys Swim Trunks

Boys swim trunks at Aaria Tees are built for action - quick-dry fabric, secure waistbands, and UPF protection make them a practical choice for any water activity. The designs go well beyond basic solid colors. The Blue Tractor Stripe UPF Swim Trunks bring a playful pattern that younger boys love, while the Camo UPF Swim Trunks deliver a bold, outdoorsy look perfect for kids who love nature and adventure. For something fruity and fun, the Red Watermelon Embroidered UPF Swim Trunks feature detailed embroidery that gives them a premium, boutique feel at an accessible price. Trunks are priced from just $14.99, making it easy to stock up on two or three pairs for the whole summer.

Swim Coverups

Swim coverups bridge the gap between the pool and everything else - a quick layer that adds sun protection during transitions from water to shore, or when kids want to grab a snack without fully changing. Aaria Tees offers lightweight UPF coverups designed to complement the swimsuit collection. The Blue Beach UPF Swim Coverup is a relaxed-fit layer that pairs easily with any one-piece or swim set, while the Camo Mallard Embroidered UPF Swim Coverup adds statement style without sacrificing coverage. Coverups are made from breathable fabric that dries fast and packs small - ideal for beach bags and swim bags headed to the pool or lake. Explore the full summer collection to find additional warm-weather styles that pair perfectly with any coverup.

Why Does UPF Protection Matter in Kids Swimwear?

Yes, UPF protection in kids swimwear matters enormously - children's skin is significantly more vulnerable to UV damage than adult skin, and standard swimwear offers almost no protection on its own. Parents often focus on applying sunscreen before heading to the water, but sunscreen washes off, rubs off, and needs frequent reapplication. UPF-rated fabric solves that problem by building sun protection directly into the garment itself.

UPF stands for Ultraviolet Protection Factor. A rating of UPF50+ means the fabric blocks 98% of the sun's UVA and UVB rays - the same rays responsible for sunburn, premature aging, and long-term skin damage. Research from the Skin Cancer Foundation confirms that UV exposure in childhood is a key contributor to skin cancer risk later in life, which is why starting early with protective swimwear makes a meaningful difference.

Specifically, UPF fabric works because of how it is woven and treated - tighter weaves and UV-absorbing fibers physically prevent UV radiation from passing through the material to reach the skin beneath. This means that as long as the fabric is covering the skin, the child is protected regardless of whether they are in the water, on the sand, or walking the boardwalk.

Comparing regular swimwear to UPF swimwear makes the difference clear:

1. UV protection level

• Regular Swimwear: ~6 to 10 UPF (minimal)
• UPF50+ Swimwear: Blocks 98% of UV rays

2. Protection when wet

• Regular Swimwear: Decreases significantly
• UPF50+ Swimwear: Maintains protection

3. Sunscreen reliance

• Regular Swimwear: High - frequent reapplication needed
• UPF50+ Swimwear: Reduced on covered areas

4. Dermatologist recommended

• Regular Swimwear: No specific endorsement
• UPF50+ Swimwear: Yes, widely recommended

Every swimsuit, swim set, trunk, and coverup in the Aaria Tees kids swimwear collection is made with UPF-protective fabric - it is not an optional upgrade but a standard feature across the entire range. This is particularly valuable for families who spend extended time outdoors during summer, at the beach, or in open-water environments where UV exposure is highest.

How Do You Choose the Right Kids Swimsuit by Age and Activity?

The best kids swimsuit combines the right fit, the right coverage, and the right style for your child's specific age and how they plan to use it - there is no single answer that works for every child. Starting with age group is the most practical approach, since fit and closure type matter as much as fabric and design at different developmental stages. Below is a straightforward guide to help parents narrow down the right choice.

Toddlers and Young Kids (Ages 2 to 5)

For toddlers and young children, one-piece swimsuits with simple pull-on closures and snug-but-stretchy fits are the most practical and protective choice. At this age, kids rarely sit still, move unpredictably in the water, and need frequent bathroom trips - all factors that make a well-fitted one-piece far more manageable than a two-piece. Look for smocked waistbands that expand and contract naturally with movement, UPF50+ fabric to protect delicate skin that burns more quickly than older children's, and designs with minimal hardware like buttons or zips. The gingham ruffle and plaid bow one-pieces from Aaria Tees are excellent fits for this age group, offering adorable style without anything that can snag or dig. At this age, sun protection is not a bonus - it is the single most important feature a swimsuit can offer.

School-Age Kids (Ages 6 to 12)

School-age kids develop stronger preferences about what they wear and tend to gravitate toward styles that feel expressive and age-appropriate - which is where swim sets and graphic trunks shine. Two-piece swim sets give older girls the freedom to move, adjust coverage, and showcase a design they genuinely chose themselves. Boys in this age range want board-short-style trunks that look like what their friends are wearing but carry the added benefit of UPF protection. Quick-dry fabric becomes increasingly important at this age, as kids often alternate between swimming and other activities and rarely want to wait around wet. The watermelon swim set, camo trunks, and tractor stripe trunks all hit this balance well - fun enough for kids to feel proud wearing them, practical enough for parents to feel confident about the coverage and protection.

Active and Outdoor Kids

For kids who swim regularly - whether in lessons, on a team, or spending full days at the beach or lake - durability and consistent UV protection become the top priorities. Look for suits made from a high spandex-to-polyester ratio that resists chlorine and saltwater degradation across multiple wears, UPF50+ ratings that hold up even when the fabric is wet (since UV protection in standard fabrics drops significantly when wet), and fits that stay secure during vigorous movement. Pairing a one-piece with a UPF swim coverup creates a complete outfit that transitions smoothly from the water to a meal break or shaded rest without losing protection. Aaria Tees' coverup range is designed precisely for this overlap, offering lightweight UPF layers that do not weigh kids down during active sessions.

Why Buy Kids Swimsuits at Aaria Tees?

Aaria Tees offers a kids swimwear collection that combines boutique-quality designs, built-in UPF sun protection, and genuinely accessible pricing - a combination that is rare to find in one place. From the graphic prints to the UPF50+ fabric to the free shipping perks, every part of the experience is designed around what families actually need.

UPF Protection Built Into Every Piece

Every single swimsuit, swim set, trunk, and coverup in the Aaria Tees range carries UPF protection as a standard feature - not a premium tier. This means parents do not need to compare labels or wonder whether a specific style was made with sun safety in mind. The protection is consistent across the collection, whether you are purchasing a $14.99 pair of trunks or a $20.99 embroidered swim set. For families who prioritize skin safety, this consistency removes guesswork entirely and makes every purchase a confident one.

Playful Graphic Designs Kids Actually Want to Wear

Kids are far more likely to keep their swimwear on - and stay covered - when they genuinely love the design. Aaria Tees invests in standout graphics and prints that go beyond the generic: watermelon embroidery, mallard duck camo, gingham ruffles, tractor stripes, and plaid bows give every child something unique to wear. These are designs rarely found at big-box retailers, which makes them a conversation starter at the pool and a genuine source of confidence for the child wearing them. Pair any swim look with styles from the accessories collection for a complete summer-ready outfit.

Affordable Prices Without Compromising Quality

Kids swimwear at Aaria Tees is priced from $14.99 for trunks to $24.99 for premium swim sets - making it easy for families to pick up two or three pieces without overspending. Free shipping is available on all US orders over $150, and new customers can take 10% off their first order using the code "welcome10" - a strong starting point for stocking up across the full range for the season. Quality is not traded away for price: the polyester-spandex blend used across the collection is soft, chlorine-resistant, and designed to hold its shape and color through repeated washes and heavy summer use.

Styles for Every Kid - Girls, Boys, and Toddlers

The Aaria Tees kids swimsuit collection covers every child in the family, from toddler girls who need snug, easy-wear one-pieces to older boys who want bold trunks for the beach. With over 120 styles across one-pieces, swim sets, trunks, and coverups, the range rarely requires shopping elsewhere to build a complete summer swimwear wardrobe. Sibling coordination is simple too - the watermelon and plaid collections span both girls and boys styles for a matched poolside look that makes family photos effortless.

Frequently Asked Questions About Kids Swimsuits

What sizes are available in kids swimsuits at Aaria Tees?

The Aaria Tees kids swimwear collection covers sizes from toddler through big kid, accommodating a wide age and size range across the full selection. Check individual product pages for detailed size charts and measurements to confirm the right fit before purchasing.

Are all kids swimsuits UPF50+ protected?

Yes - UPF protection is a standard feature across the entire kids swimwear collection, including one-pieces, swim sets, trunks, and coverups. Every style is made with UPF-rated fabric that blocks 98% of harmful UV rays, protecting children's skin throughout every swim and sun session.

How do I care for UPF swimwear to maintain its protection?

Rinse in cold water after each use, hand wash or machine wash on a gentle cycle, and always air dry. Avoid tumble drying and bleach, as heat and harsh chemicals break down the UV-absorbing fibers in UPF fabric and reduce sun protection performance over time.

What is the difference between a swim set and a one-piece swimsuit?

A swim set is a two-piece consisting of a separate top and matching bottom, while a one-piece is a single connected garment. Swim sets offer more flexibility and easier bathroom breaks for younger children; one-pieces provide more secure coverage during active swimming and are often a better fit for toddlers and vigorous water play.

Can boys wear UPF swim trunks instead of regular board shorts?

Yes - UPF swim trunks are a direct upgrade from regular board shorts because they look identical in style but add built-in sun protection that standard board shorts do not provide. For boys spending extended time outdoors at the beach or pool, UPF trunks are the smarter choice without any sacrifice in style or comfort.

Do you offer swimsuit coverups for kids?

Yes - Aaria Tees carries lightweight UPF swim coverups in several designs including the Blue Beach UPF Swim Coverup and Camo Mallard Embroidered UPF Swim Coverup, making them perfect for transitions between the water and shore while maintaining sun protection on the go.
