You better watch out, ugly Christmas sweaters.

Ugly Christmas and Hanukkah rompers are the kitschy new trend taking over holiday parties this year. And fashion site Getonfleek.com’s awesomely garish shorts sets for men in particular have been blowing up since they appeared on “Good Morning America” on Friday.

“It’s quickly becoming a must-have item this season, and we’re excited to see continued growth,” Giovanni Mannella, Getonfleek.com founder and CEO, told Moneyish. He unveiled his “ugly” holiday rompers in early November, and they’ve already become his best-selling product. He’s sold 50,000 over the past few weeks leading up to Black Friday, and now expects orders to triple as holiday parties (and SantaCons) get into full swing.

His Technicolor holiday collection includes: A red Classic Ugly Christmas Romper printed with snowflakes, stockings and a Christmas tree; a red and white Santa Ugly Christmas Romper; an Elf Ugly Christmas Romper featuring a green and red top with contrasting red and white striped shorts; a Hanukkah-themed blue and white It’s Lit Ugly Romper stamped with a menorah. They’re $139.99 apiece, but have been slashed to $79.99 while supplies last through Cyber Monday.

“It’s been a very popular gift choice this year,” Mannella said. “Ugly Christmas rompers were made for fun, laughter and enjoyment. It’s not always about fitting in or sticking with tradition, but rather an exciting new way for people to enjoy the holidays.”

There are more festive shorts sets on Etsy. And TipsyElves.com is also hawking full-length men’s Christmas jumpsuits crawling with reindeer, mistletoe and kittens wearing Santa hats for $78 apiece.

But more guys are looking to flash a little thigh year-round. Rompers have been a hit since the spring. When ACED Design launched a Kickstarter page for the $119 RompHim (their male answer to the shorts sets generally favored by females) last May, it made more than five times its $10,000 goal in just 24 hours. They sold more than 3,000 through the crowdfunding campaign, and another 2,200-plus on their official site. They’ve been such a hit that RompHim has just introduced a full-length RompSuit on Kickstarter, which has raised more than $11,000 toward its $20,000 goal. It will begin shipping in February 2018.

Reebok also offered an $89 performance romper dubbed the ReeRomp over the summer, and bro rompers, jumpsuits and coveralls also strutted down catwalks during New York, Paris and Milan fashion weeks this past fall.

“I think we’re entering an age where men are very interested in looking for new, creative ways to express themselves through fashion, and becoming much more comfortable across the board with being themselves rather than letting major brands and labels dictate fashion,’ RompHim co-founder Daniel Webster-Clark told Moneyish.

Celebrity stylist Phillip Bloch agreed. “Men are finally coming out of the fashion closet, and they’re using clothes to show their sense of humor,” he told Moneyish. “And we like things that are kitschy and corny. These ugly Christmas rompers are definitely childlike, and remind us of simpler times. And a ‘romper’ says it all in the name: It’s a romp. It’s fun and it’s carefree.”

Plus, outrageous outfits are the gift that keeps on giving for guys who want to be the center of attention at their next holiday party. “This is not an everyday item. It’s a social media-induced fashion piece made for selfies,” added Bloch. “It’s a conversation piece that everyone will laugh about.”
