Wasn't too short on me. It is swimable, I swam around in it without issue. My shoe size is 8.5 and I was able to fit in the monofin.The bikini top is meant for a kid, but if you seam rip it and move the "shells" around, you may be able to wear it? I did that but I wasn't comfortable wearing it, too revealing (and I'm just a B cup lol). I'd suggest just buying a different shell bikini top off of amazon, there are lots of affordable options.To put it on:Put the monofin into the tail. The end of the tail velcros, so slip the monofin in that way, then close it up.Gather the leg part of the tail down to the base (like putting on a stocking) then slip your feet into the monofin and pull the tail up.This tail is obviously not meant for walking, I'm surprised some reviews even mention it LOL. ### ⭐⭐⭐⭐⭐ Good value if you take care of it. *by A***M on May 30, 2018* Fast delivery and made my daughter very happy. We got a size 6-7 and it fits my skinny daughter perfect. She’s 7 but wears size 6 in her hips. A normal 7 year old should go for a bigger size. How long will it hold up? Who knows. If it’s taken care of, it should at least last a good summer I would think. I wouldn’t want her using it at the lake or on rough surfaces where it will snag and tear easy. But it’s what we wanted at a price I was willing to pay. ### ⭐⭐⭐⭐⭐ We loved it! *by D***D on June 13, 2018* My 10 year old granddaughter loved it. The fit was great! The top looked very small but it actually fit very nicely. The only suggestion I would have is to put mote Velcro fasteners on the bottom or at least larger ones. I sewed more pieces on all the way across because it kept coming open. The material the tail is out of is the nicest one we have ever gotten. --- ## 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.sn/products/167278832-xonyicos-mermaid-tails-for-swimming-with-monofin-girls-boys-kids](https://www.desertcart.sn/products/167278832-xonyicos-mermaid-tails-for-swimming-with-monofin-girls-boys-kids) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-28*
