I also don't pay much attention to pocket placement. The only thing I try to avoid are pockets that sit too low. This is what happened with my Matchstick jeans. They were entirely in the wrong spot, making my legs look short and my butt look saggy (which is quite an accomplishment considering how long my legs are and how high my bum is).
Also, what she said about the rise is so true. Some people can wear a low rise and can bend over and be fine. Others can lean over slightly in a mid rise and be exposed to the world. I am in the latter cateogory and it is sooo frustrating.
