I purchased this from the official Lululemon shop. I cut off the size tag, but I believe it was a size 2. The fabric is warm, suitable for fall and winter. Please check the photos for the fabric details. I usually wear a size 4, but I bought a 2 and it felt a bit tight, so I'm selling it. I've worn it about 3 times. It's in good condition.
