Instructions to make your own festive shirt are available here.
This festive shirt took Ugly Sweater Day to new levels, with an animated fireplace crackling away on the front.
The creator, Attosa, decorated it with miniature ornaments including a wreath and garlands made from pipe cleaners.
The fire video is displayed on a phone, secured in place by the felt hearth. Attosa says it “doubles as a phone holder for when you go to parties”, but you’d need to be careful about battery life.
