Lululemon open waterfall cardigan sweater estimated size small oatmeal colored

Lululemon open waterfall cardigan sweater estimated size small oatmeal colored. Beautiful sweater but it is missing the size tag so I’m estimating the size at a small This is based on the arms being small but this an oversized waterfall open cardigan look. The back of the sweater has a very interesting pattern knit in. Because the tags are missing on the inside I’m not sure of the material of the net other than it feels like some type of wool blend. There is a metal identifier that says Lululemon on the back of the piece #AtLeisure #Lululemon #WaterfallCardigan #Oatmeal
