I put my wallet directly down my pants. I can't stand things cramped in pockets. It's safer and much more comfortable. In addition - especially if you have a nicer wallet, it looks much nicer just to see the top of the wallet sticking out the top of your trousers rather than a giant bulge. And finally, it doesn't ruin the fabric, and you can't forget it and put it through the wash! I've never understood why guys jam the things in their pockets when you can just tuck it...
