There are people, probably in your class, that need to give loan money to their parents, to help feed their families, or to go towards child care costs. Your statements are really ignorant of a significant subsection of law students. Not everybody can have the choice of a $40 shirt or $50 on a night of drinking.
Also, to answer your question OP, wear whatever you want. Some people wear sweats, some wear shirt and tie every day. The fashion-based reputation stuff is completely overblown - your classmates/teachers are going to judge you on the way you act in class, towards your peers outside of class, and your demeanor in general. The ones that judge you on what you wear are the ones whose opinions you shouldn't care about anyway.
