TRADED Authentic Alexander McQueen Pumps

I was so excited to get these McQueen pumps, they are awesome but when I wore them out they were big on me :( I read that you're suppose to buy 1/2 up when buying McQueens but I should have sticked to 36.5 I have the box, dust bag, paper, plastic wrap and the price tag 1075 bought from saks fifth ave. I don't have a saks in memphis TN that's why I'm putting it on poshmark but if I don't get a decent offer here then when I go out of town I'll get the size exchanged.
