club-casual
Club-Casual is how you dress when you're going for dinner and then clubbing, usually with co-workers or old friends. You don't want to be uncomfortable all night, but you want to look great and be able to dance.
Wear dress pants or a skirt and sweater or golf shirt. Black or white is always hot at the clubs.
