Think 3D Father Christmases, snazzy patterns with faux fur trim and appliqué everything (snowmen, cuddly toys, reindeer, presents, trees, wreaths) across jumpers, sweatshirts, cardigans and vests. Think December's wardrobe sorted.
Prices start at £16 and go up to £25, plus (and here's the real clincher) you can shop via the brand's nifty Christmas jumper categories: 3D, bells and lights, really ugly, classic, nordic and ugly.
Here's 22 looks that we need in our life, but there are THOUSANDS to choose from.
You can buy a one-off online, in store or, if you're in the neighbourhood, you can whip into the vintage retailer's very first pop-up shop located at Old Street station in London, where it takes up residence until Sunday 21 December.
The pop-up is like all your christmas grotto dreams come true AND the best bit is that it's been pitched up to support Save the Children's Christmas Jumper Day on 12 December.
Beyond Retro will donate £1 for every Christmas jumper sold to the charity. Now that's the kind of festive spirit we love. The Christmas pop-up will be open from 8am until 8pm Monday to Friday, 11.30am until 6pm on Saturday and closed on Sundays.
To take part in Save the Children's Christmas Jumper Day sign up at christmasjumperday.org, wear your Christmas jumper on Friday December 12th and donate £2 to support Save the Children's vital work.
