Lululemon split back sweater pull over size 6

Comfy grey pull over with split back detail and thumb holes. Can be button closed, tied up, or left flowy and open. The first photo isn’t the exact sweater but shows a very similar look when button closed and looks almost the same from the front. Good pre-lives condition. Size 6 with cut out tag. The only thing I’ve ever purchased not size 6 is sports bras.
