I have 8 of them. I thought they were not going to sell the next year. They did, so I bought more. Of course the medium is tighter. I dont mind, I am 36 DD. But I am buying large now. There is also extra large if you want it to fit looser. No problem. I don't want any other shirt.I love that I don't have to cut out a shelf bra so I can wear a real bra for support.
This top was very nice but it is tightly fitted so one has to be quite small as it molds your body...I even tried the large one and it was still too tight.
