I ordered xs/s. I'm a 36c.It fit ok.It feels kinda loose because there isn't anything to hold your boobs,no pad or anything(you get what u pay for).You can always wear a strapless bra if ur more comfortable. I actually don't mind this product.I always try to work with a product however I can before returning it. You can wear it under a loose sweater, or just an oversized tshirt, even a kimono (just like I am in the pics, also from wanelo ☺️), whatever works for you. Overall I like this product. If u have any questions just leave a comment and I'll try to reply as soon as I can.
