Yves Saint Laurent vintage pinstripe suit / jacket & pants. YSL buttons

Vintage YSL pinstriped suit in beige / taupe. Buttons have YSL logo Flattering cut. The jacket is lined with Yves Saint Laurent's logo. There isn't a care tag on any of the pieces but it seems like a wool blend, maybe a wool & linen blend, and is medium weight. Excellent, gently used condition. The only flaws are small squares on the pants (see last pic). There is no size tag, but this fits my size 2/4 frame. I am listing this as size small, and some measurements are shown, but happy to provide more pics/measurements as needed.
