It's not enough to just simply be a D-bag, you've gotta let the people around you know, so I've assembled a simple guide to douchery. The easiest way to express your doucheness is with a baseball cap. You can use any of the following tactics by itself if you're just looking to add a subtle douchy touch to your appearance, or you can combine 2 or more for maximum effect.

1. leave the bill of the hat perfectly straight

2. leave the holographic/shiny sticker on the bill of the hat

3. wear the hat at an angle other than forwards or backwards

4. don't pull the hat all the way on to your head, just let it rest there

The preferred brands to pull this off are Hurley and Famous, but any ball cap will do.
