I did not find this to run too small. I am 5'4" 145 lbs and take a medium in all Transcend tops and the medium fit beautifully for this cozy zip as well. I love the length, it is not cropped and not too long, just perfect. This is quality made and super soft. More colors please!

Although description states, "regular length, sits at low hip", I found this top to be extremely short. On me it sits just 2" below my navel. You can see in the models photos, fit is quite short. Also, fit is very snug.

Think this is terrific but it fits very small. I normally wear small and it was quite tight on me. Concerned that even a medium could be too tight. I like fitted but too small is not flattering or comfortable.
