I hope there are some Buffy fans in this post...
For my formal i wanna wear the bright blue suit that 'Sweet' wears in the Buffy musical episode - Once More, With Feeling.. Thats the coolest suit ive ever seen.. plus there were those wing tipped shoes, like the ones that mafia bosses wear, hehe..
Either that or i'm gonna wear a normal suit with a bright blue or red tie, and bleach then dye my hair bright blue or red to match the tie...
