Space helmet. One that is clearly for space/underwater/extremely inhospitable environments and not just a generic helmet. I'm thinking of something that has a clear visor and is vaguely along the lines of Guy Manuel's helmet from Daft Punk.
Party hat, stereotypical birthday party cone hat.
Tricorn hat, if possible.
Trilby, for maximum meme and general cringe. And the occasional style.
Injured - scrapes, bruises, etc. Maybe black eye while you're at it?
Aviators goggles/leather helmet
Sorry if there's any repeats here.
