Another opinion, for what it's worth...
I've seen people wearing suits and dresses and thought they were crazy, and I've seen people wearing blue jean shorts and ripped tee shirts and thinking they were pigs. And I've been looked at by the people in blue jean shorts like I was crazy, and by the people in suits and dresses like I was a pig. None-the-less....
I wear docker-style shorts, a leisure shirt but with a collar (no tee shirts), and I've found myself to be among the majority most of the time. Please note, borrowing from the other posts, I go with my wife, so I'm not searching for love in all the DTD places. And I go to the AC and Comedy Club, maybe a couple minutes in the Jazz Club. Probably, it would be helpful to hear from those that spend a lot of time in the BC and Manaquins. But I think if you take "straight from the park" and clean it up a tiny bit, you'll feel comfortable, and you'll be comfortable.
And wdwnut2 hit the important thing: Get thee to the AC.
