Lululemon zip up

Unsure of the size because I couldn't find a size dot (I seriously looked everywhere) but I am confident it is authentic based on the zipper. Black and white, in good condition. No obvious signs of wear. I am guessing it is a size 4/6. Pockets on both sides. All zippers work. Smoke free pet friendly home, feel free to bundle or ask questions! Price is reflective of not knowing the exact size. Feel free to bundle or send me questions!
