"5'4 120# I got a small and it fits true to size. Shrinks a little in the dryer. If you want it fitted, it's probably safe to go with your reg size. I do wish I got the medium after washing since I don't like lengthening the straps since it lowers the front cover, and it's more comfy looser rather than fitted. I do have more of a tomboy style, though. Color doesn't run, even though there is a warning on garment that says it can. Thought I would only wear it around the house, but it's actually a spring/summer staple now"
