Great question to ask and I am happy to give you my answer!!!
Although I am petite in height and I always have to hem up every pant I buy regardless of whether it is misses or petite, I like to buy these pants and most JJill pants in misses because I like when they fit me higher in the waist and that is the case with these too. I have compared the fit between a misses small & a petite small and I prefer the fit of the misses better because I like it higher on the waist and I have found that the petite is always somewhat, all around smaller. If you can wear both and you prefer lower rise, you should buy the petite sizes, but if you are like me, prefering higher rise, go with the misses!!!
