I notice on a night out a lot of girls wear tight dresses with no pockets but they still have their phones with them and money for drinks. They aren't carrying handbags onto the dancefloor so where do you keep your phone and other stuff while you're dancing?
My cellphone is usually with a friend who has pockets OR in the closet at the club. Some clubs charge you a small fee to put ur belongings in a closet that they keep locked. I've also dance with my bag across my body before (it's usually a tiny bag made to wear across ur body) I've also snuck my bag into a friend's bag when she paid to put her things in the closet.
