Vintage 80's 90's M/L black and sparkly silver geometric mock neck knit sweater

Vintage 80's 90's M/L black and sparkly silver geometric mock neck knit sweater! Really pretty diamond mixed geometric patterns all over. Long slouchy sleeves. Longer length. Would be great with leggings or tights. Wonderful. Never got around to wearing since it's too big on me. Have tried it on and found it really comfy. Happy to answer any questions ♡♡ Measurements: Pit to pit - 20 1/2 inches across. Length from shoulder to hem - 26 inches.
