1980s YSL Vintage Black Velvet Evening Pumps Shoes - 8.5 / Black / Velvet

Hi! I’m copying and pasting the description from the site I bought them at. I received them the other day and sadly, they do not fit. They are marked as a size 8 1/2 but I think they fit more like an 8. If you know your YSL size, perhaps you’ll have better luck. They are also narrow. I cannot return, sadly. I bought them on sale for $175 so I’m trying to recoup most of that. DESCRIPTION These are timeless YSL shoes in a luxurious black velvet. Classic pump style shoes like these should always be a part of every wardrobe! These 1980's black velvet heels are from an incredible fine estate of collectible vintage designer clothing and accessories we were lucky to acquire several years ago! The previous owner had these shoes in almost every color of the rainbow! Labeled Yves Saint Laurent Paris Made in Italy. Marked a size 8 1/2 M. Excellent Condition- normal wear to sole HEEL HEIGHT: 2 1/2" OUTER SOLE WIDTH: 3" INNER LENGTH: 10" MEASUREMENTS + FIT In order to best determine fit, measure yourself or a garment of a similar style that fits you well.
