Size up! I purchased a M. 36B, 148lbs, 5’3. Ended up returning!

It runs small slightly so order a size up if you don’t want to wear it super cropped. I normally wear small/medium with a 34C chest, but ordered the large. It fits perfectly and it’s not too cropped (like the photo) There is some fabric bunching the back from sizing up, but I didn’t want it to be too short, so it’s a trade off.
