Give me a Top Hat and classy tux! I'd also love to have a blue robe and a face-concealing yellow wizard's hat. Black mage is best mage. Maybe a propeller beanie would be fun to have as well Darn, it's not letting me shrink it.
How about an Aperture Science boilersuit/test subject garb/whatever you want to call it? Something just seems to stylish about those... Maybe a Blade Runner trenchcoat? I'd suggest Doctor Who stuff, but everyone else has done it six times over... It'd probably look more like actual equipment, but something similar to Dead Space's RiG would be nice... Again, everyone's done all the steampunk suggestions, really... How about a Vault Dweller outfit? Boy, this post makes it look like I have a real thing for boilersuits... That's about every suggestion that comes to mind right now.
