Hand knit short sleeve cardigan / shrug

Lovely hand knit cropped cardigan/shrug with buttons. Extremely unique style with wide arm holes that start at the lower band (see pic.) Second pic shows more how it looks when worn. Can be worn unbuttoned like a cardigan but I usually wore it buttoned, with a fitted long sleeve top underneath. Would be great over a dress or with a high waisted skirt. Note: Missing bottom button but looks great (and lays nicely) without it if you don’t want to replace. Colour: Dark navy with royal blue wispy/hairy bits… tricky to capture in pics! Fabric: unknown (no tags but may be mohair) Size: unknown (please look carefully at measurements below to determine fit; my best guess is medium but could likely fit Small or Large too) Measurements: Pit to pit 21” Back length 16” Front length 19.5”
