1. Denim jackets or "jean jackets" as they are commonly called can be potent hipster symbols if worn properly. Find a jean jacket that fits you and prepare. 2. Put on the jacket as you would any other jacket. 3. Pull down from the bottom and pull down the sleeves. Roll your shoulders back. 4. Flatten the collar if it is turned up. 5. Close the pockets and do up their buttons if you need to. 6. Don't do up the jacket. Leave it open. Make sure you're wearing something good under it. A white T-shirt is best. 7. When you walk, lengthen your strides. 8. Insert a lit cigarette into the right corner of your mouth. People who wear jean jackets also smoke cigarettes. 9. Mess up your hair a bit. Just sweep your hands over it a bit. You don't want it too messy, just messy enough to convince people that you are a hipster. 9. Find a place with lots of people in it. 10. Walk around in it. 11. Speak less clearly. Sort of mumble a bit. Make your voice a bit deeper too. 12. Frown and scowl at people. Make them think that you don't like them. 13. Hang up your jean jacket when you're done with it. Make sure you don't forget anything in the pockets.
