Put on a rumpled plaid hoodie and old jeans. Smear some pizza down the front of the hoodie. Dab your face with ivory-toned makeup to reproduce the pallor of a four-day-coding-marathon and go as a developer.

Put on a hemp shirt and a pair of Seven For All Mankind jeans. Pick up a pair of Oakley sunglasses. Get a spray tan, grab a Vitamin Water and go as a marketer.

Put on an oxford shirt and a pair of Dockers. No food smears on the shirt, you don’t have time to eat. Knit your brow and go as a project manager.
