Here's GQ and Details Magazine's purchasing guide to skinhead wear:
Of course, this is boutique skinhead stuff, and, yes, not all skinheads are, and/or never were, neo-Nazis. (Rooted in reggae/ska culture, actually.) In any event, it was a working class thing that the fashion industry has managed to turn -- yet again! -- into a high-priced fashion feature, pointing you to Urban Outfitters, etc., to look like a skin. Yay.
