Burgundy (Red) Turtleneck short sleeve sweater. One size. I wear a small/xs

So modern and cool. Waist length turtle neck sweater in the front and long in the back. Sleeveless so looks cool with a leather jacket. The website made me choose a size. The sweater says one size on the tag. It fits loosely so I wear a size six but it stretches. The website did not have a one size option.
