I received the Marble Milk crop in Small for Christmas and love it, and immediately jumped online to buy another one. The Sunny Coast crop is just as beautiful in terms of design and quality, but unfortunately the design is slightly different and the Small was way too small for me. The underbust band is the same size as the Marble Milk crop, but there is significantly less fabric in the bust. My measurements correspond to a small per the sizing guide, but there's no way my D-cup breastfeeding boobs fit. I couldn't squeeze into it even with the straps fully lengthened. I have returned it and ordered a Medium, which I hope solves the issue, but the two additional postage charges make it a very expensive buy.
