What should you look for when buying children's swimwear?
Choosing the right swimwear for girls is crucial so your child can enjoy a carefree summer. From the perfect fit and high-quality materials to important safety features – here you'll find everything you need to consider when buying swimwear.
Fit & Comfort
A good fit is absolutely essential for girls' swimwear. This ensures everything stays securely in place and allows maximum freedom of movement – whether swimming, playing, or building sandcastles. Make sure the straps don't dig in and that the swimwear fits snugly but not too tightly.
Practical details like adjustable straps or soft, flat seams increase comfort. The right size is crucial, especially for rapidly growing children. It's best to use a children's fit and size guide to avoid buying the wrong size.
Machine-washable materials and easy-care fabrics ensure everyday usability and long-lasting enjoyment of your favorite item.
Materials & Sustainability
High-quality materials make girls' swimwear durable and comfortable to wear. Recycled fabrics or textiles with Oeko-Tex certification offer many advantages: they are free of harmful substances, skin-friendly, and environmentally friendly.
More and more brands are focusing on sustainable production and recycled fibers. This avoids fast fashion and supports a more conscious use of resources. Designs like those from MAIN Design show that sustainability and style go hand in hand.
Pay attention to care labels and certificates to ensure that the swimwear you choose is truly sustainable.
UV protection & safety
Especially in children's swimwear for girls, UV protection plays an important role. A high sun protection factor (UPF 50+) reliably protects delicate children's skin from sunburn. Many modern fabrics are specially designed to block UV rays.
Differences often lie in the material: Special UV-protective fabrics offer better protection than conventional materials. Certifications such as Oeko-Tex or specific UV seals provide additional assurance when buying.
Opt for swimwear with proven UV protection – especially for longer stays by the water or in the sun.
Care & Durability
Proper care is essential to keep girls' swimwear looking beautiful for a long time. Always wash swimwear after swimming to remove chlorine or salt water residue. Use a mild detergent and avoid tumble drying to maintain the fabric's elasticity.
Dry your swimwear in the shade to prevent fading. Quick-drying fabrics are especially practical for everyday use, as they are ready to wear again quickly after swimming.
When buying swimwear, look for robust seams and high-quality workmanship so that your child can enjoy it for a long time.
Styling tips: How to make children's swimwear a summer highlight
The right combination of girls' swimwear and stylish accessories turns every beach day into a real fashion highlight. Besides the swimsuit, accessories add flair and provide extra protection. Sun hats, UV shirts, ponchos, and beach shoes are not only practical but also complete the look. Surfsuits with UV protection, like those you'll find in our UV protection and surfsuits for kids collection , are especially popular.
Accessories and color combinations
Accessories are the perfect finishing touch for girls' swimwear. Combine swimwear with pastel sun hats, neon swim shoes, or UV shirts in vibrant colors. This creates a harmonious yet eye-catching outfit.
Examples of combinations:
| swimwear color | Accessory color | Effect |
|---|---|---|
| Turquoise | Yellow | Fresh & lively |
| Pink | White | Delicate & summery |
| Purple | Pink | Trendy & cheeky |
You can personalize girls' swimwear by choosing coordinated colors and patterns. Make sure that accessories are not only stylish but also functional.
Layering and individualization
Layering is a real trend in girls' swimwear. Lightweight ponchos or kimonos worn over a swimsuit create a cool beach outfit and offer protection from wind or sun. Ponchos are especially practical after swimming, as they quickly warm up and are easy to slip on.
Personalization is fun and adds personality to the look. Patches, stickers, or DIY accessories like homemade headbands make girls' swimwear unique. Personalized swimwear with names or favorite motifs is also very popular.
Inspiration and photography tips
Get inspired by influencer looks and current campaigns to creatively style girls' swimwear. Many designs feature bright colors, eye-catching prints, or playful details. You can find an overview of the hottest trends in our 2026 swimwear trends .
For great vacation photos on the beach or by the pool, outfits with pops of color and matching accessories are recommended. Use natural light, a calm background, and capture authentic moments to perfectly showcase the girls' swimwear.
Examples and Conclusion
Among the most popular styling combinations are MAIN Design ponchos, Roxy boardshorts, and colorful KIK accessories. They can be combined in many ways with girls' swimwear and offer variety for every taste.
Experiment with new color palettes, accessories, and layering elements to create looks that are both child-friendly and on-trend. This is guaranteed to make girls' swimwear a summer highlight!
