1970s Koret of California Plaid Pantsuit

1970s Koret of California Tan Plaid Pantsuit. Condition: Overall good vintage condition for its age. One button in the right wrist has some tarnish. All other buttons look good. Fabric is a little fuzzy with some pulling, a tiny pull here and there. See photos. I can’t find the fabric content, but it feels like it could be a wool or wool blend. I can’t say for sure. Measurements flat: Pants 11.75”-12.75” pulled taut (pictured on 27” waist - they were tight on me) Rise 13.5” Hips 19” Inseam 29” Blazer Pit to pit 19” Waist 18” Length 27”
