I purchased a medium in beige and a large in black and I loved them both, but I had to return them. Im 105 lbs and wear 34d. The large for 34d was slightly big, but the medium fit in the cup area. However, the issue with both was that the shoulder straps and the front closure did not tighten even close to enough. The bras are very soft and comfy so I highly recommend them if you are not a tiny person. If the bras tightened enough they would be my most favorite bras ever!
