I have been away from the clubs for a lot of years. Do any particular spots have dress codes? I mean I realize some dudes like to look sharp but for me it's t-shirt and shorts til I die.
Just the palace, and others don't go in paper thin clothing
I think palace DC is for night-time (after 7pm). I've been in shorts a few times day-shift.
But if they hassle you, just flip them off when you walk out the door and spend your money elsewhere.
Palace used to also be no hats but it may have changed.
