Money problems,health problems,but really want to go to the ball.I have an off the shoulder black dress,and a midriff and big bum.Dress is ancient but could be resurrected with your help.I have booked a spray tan-£15.What are those knickers called that pull your bum in?That powder stuff that leaves glitter across your chest?Is there something that will push my boobs up and make me look a bit,well,sexy?Heels,any advice?I only want your super cheap ideas,more Claire`s accessories or SuperDrug than Harvey nicks.I would be so grateful.HELP!
