Size 36 (US 6) YSL black heels

I absolutely love these open toe YSL black heels, but they are a true size 6, so I have to let them go. When I first got these EVERYONE talked about how hot they are. You can dress them up or wear them casual with jeans & a cute T. I fluctuate between 6-6 1/2, but lately I’ve been a true 6 1/2 so these are just too tight. I only wore these heels a handful of times and they’re like new.
