Going to vegas in a few weeks, and planning on hitting some of the clubs. Normally when I go clubbing, I just do the usual button-down shirt, nice jeans, and some sort of black shoes. But since it's going to be crazy hot in Vegas, can you get away with replacing the button-down shirt with a "stylish" t-shirt? I'd assume the dress-code at most Vegas clubs aren't very formal, but I don't want to be stuck not getting in. Also, on a similar note, any suggestions for shoes to go clubbing? I'm looking for something that can be worn to clubs with the "no tennis shoes" rule, but aren't very dressy either. Thanks for any help!
