Vintage Saint Laurent Cargo Pants

These are incredible, and made for a supermodel lol. Burgundy color, what feels like a cotton/silk blend or just really quality cotton. Excellent vintage condition except for one small flaw at hem of leg, see last photo. Missing the size tag, but has the following measurements - 12" waist, 13" rise, 34" inseam. Based on the existing tag's style I'd place these 70s or possibly 80s.
