Kids Swimwear Trends to Watch in 2025 – August Society Style

As we dive into 2025, the world of kids swimwear is experiencing a stylish, functional, and eco-conscious transformation. From vibrant colorways to sustainable fabrics and inclusive fits, parents today are looking beyond the basics. One brand that continues to set the pace in this evolving landscape is August Society. Known for its premium materials and planet-friendly mission, August Society’s designs are a perfect lens through which to explore this year’s most anticipated kids' swimwear trends.

In this blog, we explore the top swimwear trends for kids in 2025, all inspired by or found in August Society’s latest collections. Whether you’re prepping for a tropical vacation, a week at summer camp, or just some backyard splashing, these insights will help you choose stylish, functional, and safe swimwear for your child.

1.  Sustainability Is Non-Negotiable

The trend: In 2025, eco-friendly kids’ swimwear is not just nice to have - it’s expected.

Why it matters: More families are becoming eco-conscious, teaching their children the value of sustainability from a young age. The demand for ethically produced, non-toxic, and recyclable materials is growing - especially in clothing that touches children’s skin and is exposed to water.

August Society’s approach: All of their kids’ swimwear is crafted using recycled materials like ECONYL® and REPREVE®, which turn ocean waste and plastic bottles into high-performance fabrics. These choices lower environmental impact without compromising durability or comfort.

2.  Built-In Sun Protection (UPF 50+)

The trend: More parents are choosing swimwear with UPF 50+ built-in sun protection to keep kids safe under harmful UV rays.

Why it matters: Sunburns in childhood can significantly increase the risk of skin cancer later in life. UPF-rated clothing acts as an additional shield, especially when reapplying sunscreen isn’t always easy.

August Society’s approach: Every piece of swimwear in their kids' collection offers UPF 50+ sun protection, blocking 98% of UV radiation. From long-sleeve rash guards to full-body sunsuits, these garments protect while keeping kids cool and comfortable.

3.  Nature-Inspired Prints and Playful Patterns

The trend: From coral reefs to jungle animals and underwater scenes, nature-based prints are taking over.

Why it matters: Kids love fun, colorful swimwear that reflects their personality and imagination. Nature-themed prints not only look appealing but can also be educational and conversation-starting.

August Society’s approach: Look for prints featuring tropical leaves, reef fish, sandcastles, and marine creatures, all presented in vibrant, fade-resistant colors. These prints keep the summer spirit alive while resonating with eco-conscious parents.

4.  Gender-Neutral Designs Are Gaining Popularity

The trend: Inclusive, gender-neutral swimwear is moving into the mainstream.

Why it matters: Not all children identify with traditional gender roles, and some simply prefer more versatile styles. Swimwear that can be worn by any child provides freedom of choice and supports identity exploration safely and positively.

August Society approach: Many of their designs use neutral tones, simple silhouettes, and minimal branding, making them a favorite for parents seeking functional, inclusive swimwear. Their rash guards and trunks are equally loved by boys and girls.

5.  Comfort-Focused Cuts and Features

The trend: 2025 kids' swimwear is all about practicality, comfort, and movement-friendly design.

Why it matters: Kids are active - jumping, running, diving, and playing. Swimwear needs to stay in place, dry quickly, and avoid irritation, especially around seams and straps.

August Society’s approach: Thoughtful features include:

• Flatlock seams prevent chafing

• Adjustable waistbands for a secure fit

• Tagless labels for comfort

• Stretchy, quick-drying fabrics that hold shape and color

These details ensure kids can enjoy their water adventures without distractions.

6.  Swim Dresses & Skirted Options for Girls

The trend: Swim dresses are making a major comeback in 2025 - stylish, modest, and fun.

Why it matters: Some girls prefer a bit more coverage or love the feminine flair of skirted designs. Parents also appreciate the built-in sun protection and ease of movement.

August Society’s approach: Their popular Coral Bloom Swim Dress features a flared skirt, built-in briefs, and UPF fabric. It’s not just cute - it’s practical for beach play or poolside twirls.

7.  Long-Sleeve Rash Guards for All Ages

The trend: Rash guards aren’t just for toddlers anymore. Long-sleeve rash guards are now widely used across age groups.

Why it matters: Extra coverage equals extra protection. Rash guards reduce the need for sunscreen on the arms and torso and protect against rashes from sand, salt, and pool chemicals.

August Society’s approach: Their Reef Rash Guard Sets and Palm Jungle two-pieces combine sun-smart coverage with bold graphics and breathable performance fabrics. Perfect for both sensitive skin and all-day play.

8.  Easy-Care, Chlorine-Resistant Fabrics

The trend: In 2025, parents want easy-wash swimwear that resists fading and stretching.

Why it matters: With regular swimming lessons or pool parties, chlorine can quickly wear out lower-quality suits. Choosing high-performance fabric reduces waste and saves money.

August Society’s approach: Their entire kids’ range is chlorine- and saltwater-resistant, dries quickly, and retains color beautifully - ideal for frequent swimmers.

9. Travel-Ready Mix & Match Collections

The trend: Modular collections let families pack light and mix looks for vacations.

Why it matters: Multiple looks from a few coordinated pieces allow for quick outfit changes, easier laundry, and fun combinations.

August Society’s approach: Their Adventure Bay collection includes trunks, leggings, tops, and rash guards that can be easily mixed and matched for both style and practicality - perfect for busy family trips.

10.  Values-Led Shopping

The trend: More parents are aligning purchases with ethical values and social responsibility.

Why it matters: Supporting brands that champion sustainability, ethical labor, and conscious consumerism helps shape a better future for our children.

August Society’s approach: This Singapore-based brand transparently shares its production process, ethical sourcing, and environmental efforts. Supporting them means teaching your kids that fashion and values can go hand in hand.

Bonus Tips: What to Look for When Buying Kids' Swimwear

• Check the UPF rating – Look for UPF 50+ for best protection.

• Inspect the seams – Flatlock stitching reduces skin irritation.

• Look for adjustability – Drawstrings and elastic bands improve longevity.

• Consider versatility – Choose designs that can double for casual wear.

• Review the brand’s ethos – Sustainable and ethical brands offer more long-term value.
