Festified.com, which started making off-color holiday jumpers in 2009, claims it will sell tens of thousands of sweaters this holiday season, while UglyChrstmasSweater.com is predicting sales of 30,000 ugly sweaters. Meanwhile, San Diego-based Tipsy Elves expects to beat the $3 million they had in sales in 2013.

2009年，Festified.com开始出售颜色难看的节日针织套衫。该网站声称，他们预计将在今年的节日季中售出上万件毛衣。而UglyChrstmasSweater.com预计将售出3万件款式难看的毛衣。位于圣地亚哥的Tipsy Elves则预计会超过2013年3百万美元的销售额。

As in all things, not just Christmas sweaters, ugliness is in the eye of the beholder. But there are certain standards that ugly Christmas sweaters must adhere to, according to Tipsy Elves CEO Evan Mendelsohn.

不仅仅是圣诞毛衣，同其他事物一样，每个人眼中的丑也不一样。Tipsy Elves首席执行官埃文•门德尔松（Evan Mendelsohn）表示，款式难看的圣诞毛衣要达到一些指定的标准。

"If you are trying to go truly ugly, it's all about the embellishments -- the more garland, bells, balls, lights, and sequins you can attach to your sweater, the better," he said.

他表示，如果想将衣服做到奇丑无比，装饰物是关键。毛衣上的花环、铃铛、小球、灯以及小金属片越多越好。
