Fits perfectly. Used them few times in swim meet with her team. ### ⭐⭐⭐⭐⭐ highly recommend!! *by on Reviewed in the United States February 20, 2026* best swimsuit ever worth the price. ### ⭐⭐⭐⭐ So far so good *by on Reviewed in the United States March 27, 2026* I bought it for my 12yo daughter who is in a swim team. It’s fine however the arms are cut a bit too wide for her so her boobs pop out if not careful. She says it hugs her in the water so it’s not a great concern anymore but it seems this is the issue with some of the tech suits. Before this, I purchased the Speedo power skin and that was worse in terms of how wide the arm holes are ## Frequently Bought Together - ARENA Girls Open Back Racing Tech Suit Powerskin St Next Kneeskin Swimsuit - Arena Unisex Swim Goggle Case For Swimming Goggles, Protective Hardcover Carrying Case With Clip, Multiple Colors - arena Unisex Cobra Ultra Swipe Racing Swim Goggles for Men & Women Anti-Fog Technology Dual Strap, Mirror/Non-Mirror Lens --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/570565648-arena-girls-junior-racing-suit-powerskin-st-next-open-back](https://www.desertcart.jp/products/570565648-arena-girls-junior-racing-suit-powerskin-st-next-open-back) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
