Which are preppy stores?

When most teenagers hear preppy, they think of stores like Hollister, Abercrombie, American Eagle, and Aeropostale.

In reality, preppy fashion is the type of clothes worn by students at college preparatory schools, and is better characterized by stores such as J. Crew, L.L. Bean, and Banana Republic.


The answer above is good, except Banana Republic isn't really preppy.
Other preppy stores: Lilly Pullitzer, Lilly Pulitzer, Ralph Lauren, Petit Bateau, J.Crew, Anthropologie, Patagonia, Birkenstock, Brooks Brothers, Lacoste, C.K. Bradley, L.L. Bean, the North Face, etc.
