Vintage hand knit space dyed cardigan

Vintage handmade space dyed knit cardigan. This is a handmade piece so it does not have any tags. I am guessing this is acrylic yarn and fits a small/medium best. MEASUREMENTS (while laid flat) Pit to pit: 17” Length: 23.5” Sleeve length: (taken from neckline) 26” My measurements are 36”-29”-39” 5’5”
