In the phrase "ugly Christmas sweater," the word "ugly" is a term of art, a description rather than a put-down. One wears an ugly Christmas sweater precisely because it is so over the top, crammed with images of weighted-down Christmas trees, cartoony reindeer, red-cheeked Santas, and leering snowmen. Sequins are encouraged, as are lights. And if the sweater is three-dimensional, all the better.
