Valentino ivory flat

I bought it two weeks ago in Neiman Marcus Beverly Hills. I only worn it twice. The color was hard to get now., so this pair was shipped to the store. I have the email confirmation and the shipping tag from Neiman Marcus. The size is actually 7.5. Valentino always runs 1/2 smaller. I don't really want to sell this pair unless a serious buyer who knows how to take good care of this baby shows up.
