Price reduced on 1/22! Navy sleeveless yoga wear made of stretch material. The back is open for good ventilation. - Color: Navy - Design: Sleeveless - Design: Open back - Material: Stretch material The size is unknown because there is no tag from when I purchased it, but it's larger than what I usually wear, so I think it's around size M to L. It's a non-brand item purchased at a stall at an event. I wore it once, but it's too big, so I'm selling it. Thank you for looking.
