Costume Parties as Signaling

When I moved to Tallahassee, I noticed a big difference between Tallahassee parties and HC parties. The majority of parties I attended in Tally my first year here were themed such that attendees were encouraged, if not required, to dress up. Not that there was an absence of themed parties at the HC, it's just that there was maybe one pimps-n-hoes party to every 15 normal ones. In Tally, there are about 15 themed parties to every non-themed one. Why the difference? If you guessed economics, you must have read the title of this post...

Have you ever been to a normal (non-themed) party when some people who were not invited stopped by and somehow ended up ruining everyone's good time? I can remember everyone being sent home because some unknown dude punched an invited party-goer in the nose. There was a party from which I was fortunate enough to be absent when some kids tried to sell hard drugs then stole some personal property. I think everyone's had the experience of wondering if some of the people at the party are vouched for or if they're just drinking free booze.

Dressing up is a way to let everyone else at the party know that you are on the inside. You got the invite and prepared for the party so you belong there. This mechanism wasn't needed at the HC because everyone knew everyone else at a glance. If a stranger was spotted, they were asked who they were with. That's not so easy to do in a school a couple hundred times as big as the HC.

I went to a party in Tally where I knew one of the guys who lived there and some other invitees (who had confirmed that they were coming via Facebook). Well, these other invitees ended up going to a different party and I was there with a ton of people whom I'd never met. Luckily, I was dressed for the occasion and nobody thought that I might not belong.

Signaling is costly. It means that one must dress up for parties in Tally. This act requires forethought, perhaps purchase of new attire or accessories, and time to get dressed up. However, the benefits of keeping strangers away (and having an automatic topic of conversation with fellow party-goers) outweigh the costs in places where this phenomenon exists.
