A Christmas jumper (also Christmas sweater, or ugly sweater due to their over the top designs) is a sweater themed with a Christmas or winter-style design, often worn during the festive season. They are often knitted. A more traditional approach is a roll neck (or "turtleneck") top-pulled garment. It can generally be said that embellishments such as tinsel, reindeer, or sparkles make a sweater "ugly", in terms of ugly sweaters.
