This original 'ugly christmas sweater' is great for the holidays and parties.. Or anytime you want to look awesome and get a smile! This sweater features rudolph's cute girlfriend clarice! She is a perfect companion for light up rudolph at the holiday party! Hand crafted pattern on a 50 cotton 50 polyester sweatshirt (yes, it's a sweatshirt not a sweater, but let's be real.. Nobody says 'ugly sweatshirt!) and lights powered by a battery pack that easily slips into your pocket or waistband (requires 2 aa's, batteries not included). Oh, and if you didn't think the sweater got you enough attention.. The lights blink! Shipping standard: domestic u.s. Orders will be produced and shipped within 3 days via priority 1-3 day shipping (almost everywhere is a 2 day ship). That means from the day you order it you should expect it in your hands in less than a week! Expedited: we also offer same or next day production with overnight shipping, so if you are like me and wait last minute to get a christmas present (or ugly sweater) you can order it today and have it tomorrow! Extra 25 for expedited service. Sizes the sizes are adult unisex. Check pictures above for sizing help. If you order an xs you will get a youth size large (same sizing) washing unless you are partying like buddy the elf in the mail room this year, i don't suspect your sweater will get too dirty. However, i recommend spot or hand washing this item. The lights are outdoor lights so they are semi-weather proof, but do not soak the battery pack. Lights these sweaters are powered by a bright battery powered light set with a small battery pack that easily slides into your pocket or waistband. I do check every light set before and after i make the sweater. The lights seem to last forever. The light set i used on the very first sweater 3 years ago still works! These are led lights so they are really bright! This sweater comes with white lights. I promise you will have a great time wearing this anywhere you go. I love to make people smile and try to spread the love everywhere i go :d :d enjoy!!!
