Lululemon Boxy Cotton-Blend Sweater Heathered Vintage Plum

Slouchy yet structured, this mock neck sweater features a ribbed knit and boxy silhouette you won't want to take off. Softly Ribbed, Cotton-Blend Fabric Soft Ribbed knit texture Naturally stretchy Naturally breathable no size dot or tag but pit to pit is 20" but this is sort of a drop underarm so I would safely say that this fits like an oversized extra small to small
