I am 5β3, 135lbs, 38DD. I bought a medium and a large to start with, and kept the medium (returned the large). Since I use the shirts for layering, I didnβt want them overly loose. In all, I now have 7 different colors and I like them a lot. I wish they were a few inches shorter, but because the rest of the fit & feel are so nice, I accept the longer (for me) length. Any wrinkles from sitting in the dryer disappear soon after hanging them up.
