I'm 5'0 exactly so often buy from petite ranges aswell and sometimes the fit is just not good :/
I'm not sure if you already do but try wearing hipsters where the jeans sit around your hips and not up round your waist. I had a friend who used to do that because she had a bit of a tummy and preferred her jeans higher up to cover it, which resulted in the jeans being too far up the ankle.
You could also buy skinny jeans or slim leg jeans and just turn up or roll the bottoms a bit which is actually kind of fashionable anyway :)
