I’m 128lbs, 5’6’’ ..cup size A... ordered small... fits great!!!! I have a longer torso and can’t find many one piece bathing suits that fit well.. fits my hips well and with the ruffles makes my size A cup look bigger ... overall pleased with the suit for my pear body shape... ### ⭐⭐⭐ A little big *by L***0 on Reviewed in the United States 🇺🇸 on February 8, 2020* The color, style and material looks good. I just received it and shipping time was fast, a couple of days. It looks as if I can wear it as a top as well. The only thing I found it was a little big on the stomach area. It didn't pull tight enough. But its not too bad. For the price I am keeping it ### ⭐⭐⭐⭐ Cute! *by K***R on Reviewed in the United States 🇺🇸 on July 13, 2020* The skort is comfortable and cute! --- ## 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.co.uk/products/401187758-thermal-underwear-for-kids-boys-performance-athletic-compression-base-layer](https://www.desertcart.co.uk/products/401187758-thermal-underwear-for-kids-boys-performance-athletic-compression-base-layer) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-02*
