For formal nights I think what one would wear to a corporate office setting should suffice. Meaning that shirts are button-down or at least not t-shirts or tank tops. Pants are clean and no holes and affixed to the waist (jeans are fine just not dirty, holey jeans sagging on the floor). No flip flops. If someone wants to wear something nicer like a tux or a fine gown that should be fine but not expected. Economically it doesn't make much sense to many people to spend a bunch of money on things they will typically not wear on a normal basis. Please note this is only for formal night. If you wear cutoffs, tank tops, and flip flops in the MDR on NON-formal nights I don't care. Not my style but you do you. Moreover, on non-formal nights there is no expectation to be had that people will looked more cleaned up.
