Fashion hack: avoid wallet butt bulge - Lifehacker
A silly, but important thread over at one of my regular reads talks about wallet-bulge on guys, and how it ruins the topography. My $.02, (since I don't have commenting rights over there... hint-hint!) is this: go with a really slimmed down money clip in the front pocket. I use one that allows me a cash clip, an outside-visible clear pocket for my license, and inside spots for 4 cards, plus I use the foldy space in between for receipts. No wallet bulge. No painful butt from sitting cock-eyed for long periods. No scrambling for 'where'd I put that card...' again. Other useful, but seldom-used cards (library, video store, etc.) stay bundled in the car for easy access.
