I wear shades when I'm working. I have the light off, and the only light in the room is the computer screen. The shades help me to focus, as it blocks out any other light, and I get "tunnel vision" with the screen, to where it's all I can see.
Normally you'll find me with shades and headphones on. ;)
As for "club" attire... I have some, but, I normally just wear a T-shirt, cargo pants or jeans, a ball cap to keep the hair out of my face, and my Addidas. That's about it though.
Cheers!
