So I just received my Louboutin black bruges today--and they are 1/2 a size too big!! I asked the seller if I needed to go up a size (I usually wear a 36.5) and she reccommended a 37. I emailed her today and asked if I could do an exchange and she said I could, but that it would cost $40 extra (plus I'd have to pay to ship it to her), and I've already spent so much money on them. What should I do--just buy an insole or should I spend the extra money? Thanks girls!
