Vintage Shimmery Pink Heels

These really cool vintage heels are clearly old (vintage) but I think they still have a lot of life left in them. They are not perfect and have some flaws (mild scratches + signs of wear) but are overall very nice! I would love to keep them but they are slightly to narrow for my feet. I would say they run a bit small. They color is pink but has some interesting metallic shimmer to it. I don’t know what the actual material is.
