gly Christmas sweaters usually involve garishly colored yarn and motifs of reindeer and Christmas ornaments. Sometimes festooned with actual ornaments and perhaps a sprinkle (or bucketful) of glitter. They are ugly because, Christmas sweater ugliness is as American as hotdogs and processed American cheese slices. If you’re concerned that your Christmas sweater is ugly, it probably is. Embrace the hideous and wear your Rudolph sweater with pride. Add sleigh bells for an added, jaunty accessory.
