I have some cuffed pants and I'm only 5'0". I also don't think I have particularly long legs, proportionately speaking. I haven't worn them in awhile, but when I have, I always got compliments, so I have to imagine they aren't that bad!
They are form-fitting in the hips and thighs, but then are wider at the cuffs. I would call them wide-legged. I wear them with heels, and they nearly touch the ground. (PPL).
So I would think it's one of those "it depends" things... cuffs are usually and generally difficult for someone our height, but every now and then, with just the right fit, it can work.
As a general rule you definetly want to wear them with heels, and you want to be really, really careful with the length. You can't fudge the length at all and have them a little on the short side. They should nearly sweep the ground, with very little shoe showing.
