I'm 5 foot 1 and typically 14-16 in size. The 16 petite fitted me as expected, ie a little big. But what I didn't expect for such an expensive pair of leggings was that it wasn't made of very stretchy / elastic material! Even supermarket leggings are made of stretchy material. It meant that I kept having to pull it up whilst out and about. Wouldn't recommend. Though, stitched well etc. Might just wear it for bed, lol.
