I'm always finding myself in need of some advice on what/what not to wear, so I decided to ask TFP for once. Its almost time for classes to start up again, and I'd like to look nice with a few pairs of new khakis. Yet I'm stumped by all the choices, flat front or pleated seems to be the biggest decision. Is there any rule about how to choose which style, or should I just see what looks better?
