Pullover sweater

Unisex pullover sweater with colorful abstract design. Off white with geometric shapes in red, blue, green, black, grey. Fiber unknown, but material is soft and not itchy so guessing acrylic. Some pilling throughout, and yellowing around the collar, I have not attempted to remove. Really fun vintage sweater, perfect for fall and winter. Approximate measurements: Pit to pit 19.5” Back of neck to bottom 27 1/4” Shoulder to shoulder 21” Sleeve length 22”
