in-demand ! Vintage 1980's Cristina black high waisted skirt <3

Dates from the 1980's, used, size 11 in women's (I normally wear a size 10 or 11 and while it fits really well on my waist I had trouble getting it past my thighs and butt so if you're curvy like me i'd size down and if you're not you should be good but it looks like it'd be effortless to resize), not sure what it's made of that part of the tag is really faded, the buttons on the front are just for decoration (all of them are still here), opens and closes with a zipper in the back which still works, and is in good condition but still does show normal signs of wear and tear from age and use (fading, there's holes in the fabric on some parts, loose strings, etc).
