NWT dark blue novelty Christmas sweatshirt. Maybe it's perfect for your next Ugly Christmas Sweater party, or maybe you really like Coca-Cola and Santa? Battery pack is concealed in a small pouch on the left hip, and inside of sweatshirt has a lightweight inner lining to protect the wiring for the 6 LED lights. See all photos and tags. Size XL, but unsure if sizing is M/F/Unisex - measures approx 26.5" long and 23.5" wide across the armpit Tag says Charcoal, but it's pretty clearly a dusty/muted navy blue (I removed the "I light up" sticker after these photos to be sure there was no residue left - all good!)
