Choosing a kids’ Christmas jumper

Comfort comes first. A child who finds their jumper itchy will have it off by break time, so soft cotton-blend sweatshirts are often a better pick than chunky acrylic knits for younger kids. Look for roomy necks that go over heads easily and cuffs that won’t ride up.

Think about the day too. For Christmas Jumper Day at school, a washable sweatshirt that can cope with lunch and the playground makes sense. For a party or family photos, something with a bit more sparkle or a light-up feature is a lot of fun.

Boys’ and girls’ Christmas jumper styles

Light-up jumperSchool discos, Christmas lights trips, the Christmas partyCheck the battery box is secure and remove it before washing
Character or hobby design (trucks, gaming, animals)Kids who want their jumper to be about themThe safest way to get a fussy child into a jumper
Classic reindeer or Santa knitFamily photos, visiting relatives, Christmas DayWarmer but can feel scratchy; pop a T-shirt underneath
Retro or Fair Isle styleMatching family looks, older kidsOften sized as unisex, so check the age chart
Matching family jumperChristmas cards, Christmas Eve photosChild and adult sizes rarely line up, so check each one

Older kids and teens often prefer something closer to an adult jumper, so a subtle knit or a funny slogan can go down better than a cartoon design. For toddlers, skip anything with small stuck-on pom-poms or bells that could come loose and end up in a mouth.

Sizing tips for growing kids

  • Buy a size up. Kids’ sizing often runs small, and a roomier jumper should still fit next December.
  • Check the age chart. Ages are only a guide, so compare chest and length measurements with our costume size guide.
  • Wash inside out. It keeps prints bright and reduces bobbling, especially on knits.

More festive fun for kids

Want to go further than a jumper? Little helpers love our elf costumes, while mini Father Christmases are covered in our Santa costumes. Light-up antlers or a Santa hat from our Christmas accessories finish the look.

What size Christmas jumper should I buy for my child?

Use the age as a starting point, then check the chest and length measurements on the listing. Kids’ jumpers often come up small, so buying a size up gives them room to grow and to wear a T-shirt underneath.

Are light-up Christmas jumpers safe for kids?

Most are fine for school-age children, but check the battery compartment is secure and can’t be opened easily by little hands. Always take the battery pack out before washing.

Do kids have to wear a Christmas jumper on Christmas Jumper Day?

No, it’s just for fun and usually linked to a small donation to charity. Many schools are happy with any festive top, or a regular jumper with some tinsel or a homemade decoration added.

How do I stop a Christmas jumper being itchy?

Choose a cotton-blend sweatshirt rather than a chunky acrylic knit, and wash it once before wearing to soften it. A long-sleeved T-shirt underneath helps for sensitive skin.
