Yves Saint Laurent Black Strappy Heels size US12 or IT42

Very good condition black velvet strappy heels from Yves Saint Laurent YSL in size 12 or IT 42. Heel is 4.25 inches high. Yves Saint Laurent fits a little small to other designer shoes so consider ordering half size to one size up. I am a size 10 in regular street shoes and size 11/11.5 in designer shoes (manolos, jimmy choo)
