Lululemon ribbed sweater that can be worn with crossover hem in front or back. Unsure of numerical size but I estimate it would fit a size small best to get a relaxed fit similar to the model photos. Measures 17 inches pit to pit and 19 inches long. Gently used, some light overall wear, no holes or stains. Bundle and save! Buy 2 or more items from my closet and get a discount!
