Hair: Longish, not too long, about Kurt Cobain length, brown, very messy. In the winter I wear beanies (usually Animal or my peaked Billabong one, I've also got some band ones)
Top: metal/rock/ska band t-shirt/ longsleeved tshirt, or Plain Lazy, Animal, Saltrock that kinda thing. Generally same for hoodies too. Occasionally a leather jacket if I'm on my motorbike or it's cold, occasionally with a hoodie underneath.
Bottom: Baggy (not too baggy, but I can't stand skinny jeans) jeans, usually dark blue/grey/black or camo trousers if I'm mountain biking, hiking or at a metal gig.
Shoes: I have a pair of German Paratrooper Boots I got from an army surplus store, I wear them at gigs mainly. Usually I wear skate shoes; Globe, DC, Ripcurl, Vans.
Other stuff: I've got some band sweatbands I wear a bit (Misfits, Metallica, Killswitch Engage), and some fingerless gloves (not leather ones, no studs. I'm straight), I do have some aviators, but I rarely wear them.
