Vintage Chanel Skirt

Late 1980s vintage Chanel midi-skirt with side pockets and pleat detail at front. Size and fabric tags have been removed, but the fabric feels like a wool blend, and in my opinion it fits like an XS. The color is a gray-toned muted blue. There is wear to the stitching on the Chanel label, some loose threading at the top of pleat detail, as well as in one of the pockets. I have had the skirt authenticated by Lollipuff, but have this priced at $500 in case a buyer would like to have it authenticated by Poshmark as well. Otherwise I’m open to reasonable offers.
