i know this sounds like sarcasm, but honestly, if you're looking to hook up you're bound to get more attention with this outfit than something dapper. not even joking.
Yeah I wouldn't worry about looking good down there. Just wear shit that's comfortable because it'll be hot as a motherfucker. Most dudes will be wearing tank tops and shorts/cargo shorts during the day and some bright ass Robert Graham type of shit at night. Rambo has it right. Chicks down there definitely aren't looking for Steve McQueen.
