Let these ugly Christmas sweaters warm your heart

’Tis the season — to be tacky.

While you may love the Christmas season for the parties or the chance to be with loved ones, others enjoy it because it’s the only time of year outside of Halloween they can dress ridiculously and not be mocked. Openly, at least.

Here’s to the ugly Christmas sweater.

According to the “Ugly Christmas Sweater Party Book,” the trend really started to take off around 2001 — no doubt coinciding with the rise of Brooklyn culture and hipster irony. Now, hideous jumpers that once might have collected dust at the local Goodwill are suddenly fashionable.

But finding them no longer means digging through a thrift store. They’re stocked in chain stores, including H&M and Kohl’s.

The Post tried out five looks you might want to don this week and rated them on a scale of 1 to 5 stars — 5 being the most wonderfully ho-ho-horrible.

If you really want to go all out …

While technically not a sweater, this festive red number from OppoSuits is what we’d kindly call a “conversation starter.” Unkindly, we’d say it’s gloriously tacky. Show up at a family get-together and watch as anyone in regular Christmas attire turns green with envy. $100 at opposuits.com and macys.com

It talks to you!

We’re not sure why anyone would want to wear a sweater with a built-in padded belly — and, to make matters worse, this one plays sounds. Press Santa’s tummy and he loudly exclaims, “Merry Christmas and a Happy New Year!” Wear it in public, and we’re guessing people will push the belly so many times in a row, we’ll all go insane and Christmas will be canceled. $30 at macys.com

Inspired by your favorite movie!

It’s Grinch-green. It’s 40 percent acrylic. It’s got the ugly lamp from “A Christmas Story” on it — with real fringe. But the most novel part is that it lights up — via several tiny bulbs embedded in the lamp shade. $66 at tvstoreonline.com

The vintage throwback!

For a return to the days when only 9th-grade math teachers wore Christmas attire, head to the East Village’s Metropolis. The vintage store stocks hundreds of ugly sweaters and vests — mostly of the ilk that were sold at middling women’s clothing stores in the ’80s and ’90s. $45 at metropolisvintageonline.com
