I'm a petite (5'0) apple as well. I got my jean jackets several years ago, but if I had to replace, I'd go the same route: petites! The fit and detailing is more precise for us shorties.
I have a white jacket from LOFT, a dark wash/slightly faded from LOFT, a light blue cropped style from Old Navy. All get plenty of wear. I wear the LOFT ones the most year-round, whereas the ON jacket gets a ton of wear in the summer, because it's very lightweight. It was also the cheapest so I don't baby it as much as the LOFT jackets, routinely getting balled up into my beach bag, getting sunscreen all over it and then sending it through the wash and the dryer, whereas the LOFT ones never go in the dryer, because I'd cry if they shrunk! My daughter who's very busty and 5'3" has the exact same ON jacket as well.
I'd suggest focusing your search on LOFT petites, GAP petites, Banana Republic petites, and Ann Taylor petites.
