I'm 5'4" with very short legs and a small frame, and I wear them. I always get a lot of compliments on them.
The cover image of the first Sartorialist book is a woman in stunning wide-leg pants and I believe she's around 5'3".
I think a true petite would do better than me, with my short legs and long torso. I think I wear it best with higher waists, though the A+O trousers I have are low rise (but amazing otherwise).
