Childhood sun protection matters. Our UPF 50+ fabric blocks at least 98% of harmful UV rays where it covers the skin, helping reduce UV exposure during beach days, pool time, and outdoor play.

This swimsuit was great! I had it made for my daughter to wear on a cruise, and it was perfect. The fit was as expected. The only issue I saw was that it’s slightly see through at the back once it gets wet. Nothing too bad though

Amazing quality!! My daughter LOVED her suit

Great quality. Arrived early. Product exactly as pictured

Super cute bathing suit. It looks exactly like the online picture. My daughter loved her bathing suit for her birthday in Jamaica 🇯🇲

5th birthday candle cake swimsuit

I was so disappointed I didn’t receive these swimsuits in time for my twin granddaughters to wear for their fifth birthday pool party because they were simply adorable & very well made. I was given a full refund for this purchased & allowed to keep the swimsuits. Even though they won’t be able to wear these again I was happy to get a picture of them in the swimsuits to remember their fifth birthday. I will gladly order from Bouvelle again.

Outstanding!!! I waited a little to test this item before my review, I was a little nervous about this product because it was white but not to worry the material is soft and strong not see though, but most importantly the bathing suit Dried fast,my daughter it pretty petite and is always cold so drying is important to me. I will say the sizing it true to size so 2t fit just right on her and I got so many compliments will buy other items from this store highly recommended. Lasted though a water park experience!!!!!!!!!
