dressing up Fallen can be fun! He doesn't have much verity in his clothing, usually wearing a jean and hoodie combination. His rave clothes include a rave mask, some reflective pants, and wrist warmers. (glowsticks optional)
For formal events, he does own a grey and blue suit. Cleans up rather nice, actually.

sorry this pic is so blurry, I'll upload a better version once I can afford to get my phone fixed.
