Don't big nights out always go wrong? You pop to the bar only to get pushed and shoved to the back of the queue - then when you've finally been served you've got to face walking round and round a dark club to find your friends again - none of whom ever seem to have a phone signal. Well all that could be at an end - just tell them to look for the girl with the glowing handbag!
Alexander Wang's white leather shoulder bag magically transforms into a glowing green beacon after dark - now that's a partypiece if ever there was one!
