For a dive bar, t-shirt, jeans and shoes are pretty much par for the course. I don't recommend sandals, as shoes offer a little more protection. If you want to, you can always dress up a little and be the classy girl in the place, but I wouldn't go overboard. Remember the people who are there; you've got frat boys who are partying their butts off for cheap, locals who just want a drink after a hard day at work, guys like me and my Brothers in our leather jackets, as well as folks who've been there since it opened at 11 am. If you just do that little bit of dressing up, you'll stand out in a good way without standing out in a bad way.
