Well, according to the section dedicated to fashion in the Attitude book, the clothing in 207X can be broken down into four categories: Casual, Business, Formal and Urban.
Casual clothing is everyday wear for most when they're not working. Jeans, Tshirts, skirts, running shoes, etc. it can range from Horizon's 6 Tees line (American Eagle style clothing) to Monobe's NuZoot (Asian monogrammed clothing).
Business clothing isn't far different from its real-world equivalent. 1-3 piece suits for men, pantsuits or skirt suits for women, etc. Evo's MetaTribe line (a variety of uniforms) and Saeder-Krupp's RhineGold (old world-style three piece suits) can both be counted among this category.
Formal is the classy stuff that you use to (try to) pass for normal in high-society and various events. Far and away the most pricey clothing, this group covers designer clothing (Armanté, Berwick, Zoë de Paris, etc.) and 5k¥ gets you the low-end stuff.
Urban is pretty much Casual with one big difference; where Casual clothing emphasizes blending in with society, Urban makes it a point that you're going to stand out. "This is the stuff you wear clubbing, not working." Evo's ME MetaL and NeoNET's Furba (faux lether jackets, graffiti-patterened shirts, etc) lines are both good examples of the genre.
The book also covers a wide variety of accessories (acoustic clothing, AR makeup, watches and hosiery) and trends (post-apocalypse, steampunk, body modification, etc.). It's really a great supplement and not just for fashion. If you're able to get a hold of a copy, I'd highly recommend it. I hope this has helped.
