Hollister and Abercrombie are some of my favorite stores. (I'm younger, so they're popular with kids my age.) Hollister Jeans sizes start at size 00 and then go to 0, 1, 3, 5, 7, 9, and 11. Abercrombie and Fitch jeans start at 00 and go to 0, 2, 4, 6, 8, 10. I find it weird that they don't just have the same sizing, since they are owned by the same company. Fitting int smaller Hollister jeans is a great motivation for me, I'm trying to get down to a Hollister 1.
