I don't really get it. Why the hell would you dress up like it's a wedding.
Hmm different traditions I guess. But still wierd.

Graduation from school; they're usually really formal, the after parties at least. All the guys dress in tuxedos and dress clothes and the girlies all wear dresses and shit. Some school events call for formal dress only, and if you wear jeans and a metal band tee-shirt they'll yell at you.
