I bought this a couple of months ago and suddenly it seems to be a size too small for me! It is a Medium and NEVER BEEN WORN - there are no tags. Brand new, pristine condition. It is an absolutely beautiful vibrant color. Medium size. And this is the description from the website: If you can’t be bothered to pick both a sports bra and a top, we’ve got just the thing. The Gemma Scoop Tank has a built-in bra and double-binded straps to keep you supported, plus a silhouette that fits like your favorite tank (a.k.a. it has an open neckline and won’t be too tight through your mid-section.) Move over, other workout tops. Gemma has arrived. Made from 79% recycled plastic bottles (RPET) and 21% spandex Recyclable with ReGirlfriend Built-in bra for low to medium-impact support Scoop neck and scoop back Straps with double binding construction give a secure fit while keeping the neckline open Designed to cover the top of high-rise bottoms and be fitted around the bust and armhole, but not super tight through the body Soft yet sturdy construction with four-way stretch To take care of it, machine wash cold and hang to dry — we recommend using a microfiber filter or filtering wash bag. ;) Please note colors may bleed at first, so always wash with like colors in cold water.
