BCBG size S/M black and white open long sleeve knit cardigan! Longer on the sides and draped front. Worn open. There is one large decorative button but I can't find a button hole for the life of me. Maybe just decorative. Soft and comfy! Super cute!! Wonderful condition. Happy to answer any questions ♡♡ Measurements: Pit to pit - Open. 17 1/2 inches across with it closed mostly. Length from shoulder to hem - About 23 inches for shortest part and 35 inches for the longest part.
