the first time i had to wear a suit I thought it would suck too, but people just kept telling me how good I looked and it really was pretty comfortable. I think it's good to dress up once and a while when you're just hanging out, or meeting someone somewhere or whatever. Especially if you're meeting a girl somewhere to grab a bite to eat or for coffee or something, they usually don't expect that and it shows you took time to think about them and dress up.
