Preppy, especially with layered sweaters/shirts. One piece items, those two in one tops that look like a shirt layered underneath but really is not, in general less layered looks.
Jeans, sweatshirts, fleece, sneakers (especially white one's), prints, lots of color, looser fit, lighter colors (unless we are talking east coat, then lot's of black), less quality and more quantity. It's very easy to go into a store and walk out with a gallon of milk and a new top.
