This is a very stylish, and practical, vintage 80s Saint Laurent wool shift skirt. It is fully lined and, interestingly, it buttons up at the back of the skirt. It is a high waisted skirt and falls just at the knee. It is fully lined and the weight of the fabric (no fabrication label, but I believe it to be a lightweight wool, means you can wear it all year round. There are sleek pockets just a little above hip level.
It is a FR42, approximately 12-14, see measurements in inches below:
Waist: 30″
