Lululemon All Tied Up tank black size 4

Black Lululemon All Tied Up tank. I removed the size tag but my guess is it’s size 4 - can be adjusted to be looser or tighter by the tie in back. I’ve had this and several other colors for years. It’s been worn a lot and is more of a faded black now so I’d say it’s GUD. Fabric is more cotton-y than athletic.
