Now this is a genius idea to get traffic in your store, tell them to show up in their undies and bra for free designer clothes!  Kudos to Desigual in Paris! 

Ofcourse, it's only for the first 100 to show up, for for the rest who came in only their undergarments, who wouldn't buy clothes before they leave!  They should make this an annual event, I'm down!  check out all the half naked shoppers here
