I'm 5'2 and based on some other reviews i opted for the regular rather than petite and am glad i did. even the regular is kind of short. if i raise my arm(s) all the way up, skin is typically exposed. i originally ordered a medium and i liked the fit everywhere except for the chest. i'm a 34dd and i felt like i couldn't move my arms. i exchanged it for a large to sacrifice some of the fit for some more arm movement. the cut is already a bit boxy so having it a bit boxier with more arm movement w
