Hi Maya, I'm also petite. My suggestion is to try on petite jeans - you may find that makes all the difference!!
Both Ann Taylor and Ann Taylor Loft carry trouser jeans styles in petite. I have a pair from Ann Taylor that have slit side pockets and they are wide but not -too- wide in the leg, with a slight flare at the bottom. And I have a pair from Ann Taylor Loft that also have slit side pockets but drop straight down from the hip, so you get that wide look but it's proportioned to your petite frame. Tip: Hem these really long - practically touching the ground - for the best look.
I also second the recommendation for Tahari pants. I don't own the jeans but I have tried them on - the fabric is very lightweight which I think works best for petite frames because it adds no additional bulk. Otherwise, I have THREE pairs of Tahari slacks (white, tan, and a khaki green) that I got at Marshall's. I can't wear them now that I lost weight, but they were my go-to-pants 20 lbs ago because they are soooo flattering. Not just in the legs, in the butt!! They will make you look very sleek and even TALL.
Finally, on the higher end, check out Citizens *Hutton* jeans. Not petite, but they work on my 5'0" frame. Had to have them hemmed though. These are not necessarily trouser cut - more like a flare cut. Still, they work nicely and are my current favorites.
However, if you want a true trouser cut jean, my first recommendation is to check out Ann Taylor petites. Good luck!
