Basic Colors: workplace grays/blues/tans, for looking sharp without making too many waves
Pinstripes: well, you’re making a few waves now, aren’t you?
Checks & Plaids: you’re pushing boundaries, but you’re not blowing boundaries up
Tartan: you’re wearing a kilt as a suit, and it’s awesome
Colorblocking: you’re a male runway model; also, you’re wearing sneakers
Not all of these will work for everybody, but if you’re not senselessly blowing tons of money on one suit, you can buy many suits -- and if it turns out you can’t pull one of them off as well as you thought you might, you’ll still be able to put your future children through four years of college and one year of screwing around in Colorado.
