I haven't seen any of these in person, but Anthro has a lot of petite jeans styles (although not all of their stores carry petites). Some finds below, and the whole page is here:

(Of note, they seem to have a lot of petite CoH, AG, and Paige styles, which are hard to find elsewhere. Plus their own line, Pilcro, always comes in petites.)
I don't actually need petites in jeans (I have long legs) but I find I tend to prefer it in crops because I don't wear heels and I like them a little shorter. Plus the rises are shorter, which is one way to get around the whole high rise thing (which I dislike greatly). For example, my olive culottes are petite.
