This is the assignment I gave the models:
Imagine you had to caricature yourself- however you define yourself (be it your interests, style, sports, where your from- whatever you want) that is how I want you to dress. This does not mean typical you- this means exaggerated you- this should be 75% more highkey than the way you dress any regular day (your outfit should make people feel like they walked by a fully dressed supermodel/weirdo on their way to the cafeteria).
Whatever you are but on steroids.
