1970 Yves Saint Laurent YSL grey straight skirt size 6. (Vintage sizing)

I used to collect vintage designer wears. This is a beautiful fully lined pinstriped straight skirt from the 1970s made by YSL. Made in France. High waisted with a side zipper and button closure. Simple darts on the front and back - very simple and classy design. The skirt is still in an amazing condition except a small rip at the bottom of the lining at the seam as in the photo. It hits me at the knee bc I’m literally 5’ so I don’t do it justice. Tag is a little worn out so I can confirm material but I think it’s a wool poly mix. It has no stretch like most classic suiting. Vintage sizing size 6 but equivalent to a size 25/ size 0-2 imo. Ask for measurements if you’re interested please!
