Lululemon Unity Drop Back Sweater

Lululemon Unity Drop Back Sweater Cashlu fabric (cashmere blend) Smoky Blush Great shape, light signs of wash/wear No size marked, it was sold to me as a 6 and when it arrived I thought it was an 8 for sure, however I checked the one I already own and it’s a 2, so perhaps this is actually a 6 but just fits a bit big. Pit to pit is approximately 19”
