100% authentic Chanel and karl lagerfeld vintage blue and black wool

This is a gorgeous unique 100% Authentic chanel skirt , vintage from 1999/2000 collection. it is a perfect match to the Chanel blazer/jacket in my closet. hard to find from chanel and karl lagerfeld. This lovely skirt w the jacket (in other listing) belonged to my dear grandma but doesn't fit me! the skirt tag isn't on anymore I believe it was removed during waist alteration, but I've written down the exact measurements and I believe it equals a size M or 10/12. Here are the flat measurements: 16" waist 19"hips 23" length thanks for looking pls let me know any additional questions you may have:)
