gap ankle length is usually a nice length for me (though i don't like the way they fit me, so i don't own any). plus if you wash them, they usually shrink maybe 1/4 to 1/2 inch.
some places will tailor in the same day...maybe that could be an option if you need the jeans right away?
I second AE. I went to every store at the mall last weekend all the pants were sooo loong! AE jeans in petite were perfect. If you do go make sure to take that printable coupon they posted. coupon
I also recommend AE petite length. The new styles (I like the Curvy ones) at Gap in ankle length are good, but for some reason the ankle length in their original style are waaaay too short. Of course the regular length is waaaay too long. I also sometimes have good luck with Lucky brand jeans - some of their regular length jeans are short enough for me to wear with flip flops. Express also has a short length and a variety of styles.
Good Luck!
