Step 1) Shoes, Black: Probably want to wear some Aldo's or something along that line.
Step 2) Dark blue "designer" jeans. Make sure they cost at least $100.
Step 3) Hair should not be any longer than optimal spiking length. Make sure it is gelled too.
Step 4) Clean-shaven is a must; no facial hair allowed.
Step 5) White button-down shirt, generally lightly pin-striped in blue. Most importantly make sure it is not tucked in.
Step 6 (optional) Wear a navy blue sport coat/blazer to go with your dark blue jeans. This will really cap off your outfit.
There you have it! Follow these steps and you will be on your way to trendiness no matter if you're fat or skinny, likable or not. I'll see you there!
