Match the whole family for this year's Christmas card and steal the show at every party! From the Women's Prosecco Christmas Sweater to the Men's Prosecco Christmas Sweater, there's a glowing design for every taste in our collection.

What makes our ugly christmas sweater with lights worth wearing

Every sweater in this collection has 12 flashing LEDs woven right into the design, so the whole thing glows once the room dims. The flagship is the Prosecco glow knit, in both a women's and a men's version, but the range runs across plenty of festive prints. Pick one for yourself or grab two and out-sparkle each other at the party.

The lights are the fun part. The practical part is that they behave: flip the switch off and the small LEDs sit see-through against the knit, so it reads as a normal (if loud) Christmas sweater until you want the show to start again.

How the lights work on every ugly christmas sweater with lights

The 12 LEDs run on two tiny CR2032 watch batteries that slot into a removable battery pack, giving you roughly 20 hours of light per set. Batteries are sold separately, so add a pack to your cart before checkout. There's a simple on/off switch on the battery pack, and because they're LEDs the bulbs never get hot, no matter how long the party runs. If you've ever searched for a sueter navideño con luces, this is exactly that, just with the practical details sorted.

Washing and caring for your light-up christmas sweater

This is where we beat the dry-clean-only crowd. The battery pack lifts straight out, so your sweater goes in the machine like any other knit. Wash it on a gentle cycle at a maximum of 30°C, inside out and with like colors, then dry it flat to keep its shape. No tumble drying, ironing, bleach or dry cleaning needed. Pop the battery pack back in once the sweater is fully dry and you're ready for the next round. Every light-up sweater is also covered by our two-year guarantee.

Fit and sizing

These are a regular fit, so go with your usual size. If you're between two sizes, size up for a little more room, handy if you're layering over a shirt for a colder party. When you want to browse the wider range, our full collection of christmas sweaters has plenty more beyond the glowing ones.
