Vintage 60s 70s Tweed Woven Sleeveless Midi Dress

This lovely tweed dress is from the late 60s or early 70s, and features a slight v-neckline, darted bust, buttons at the back, and a wrap-around skirt. It hits at knee length and is lined for comfort. Branded World Famous Graff Californiawear, this dress fits a 40" bust, 32" waist, and 41" length. I believe it is wool but there isn't a tag indicating whether it is. The dress has a few snags right where the hook and eye is (it's in the back so it looks like it got snagged as someone was trying to do it up behind their back) and has belt loops but not a belt.
