Dirk Bikkembergs Men's Sz. S (athletic M?) Knitwear S/S Shirt Black w/Graphics. Well cared for and in exceptional pre-owned condition. This is 100% and has the feel/texture of a light sweater. There is no size tag but the measurements equate to a size small. It might work as an athletic medium, but not that the shoulder-to-shoulder measurement is 16". Please use the other MEASUREMENTS IN PHOTOS and compare to a similar piece you own. If there's another measurement you'd like, let me know. Ask all questions before offer or purchase and consider pictures as part of description. I will list any issues I find.
