This is the Ivivva by Lululemon Dream Embracer Hooded Wrap Cardigan Sweater. It is reversible and turquoise and grey. Because it is reversible, the tag was removed. I believe it is a size 12, although it may be a size 10. Armpit to armpit measures approximately 17 inches. Excellent condition with no known flaws. Thumb holes at the bottom of the sleeves.
