Newborn Christmas Outfit Ideas for Girls

You can’t go wrong a little Santa baby outfit, complete with striped stockings and a Santa hat! What could be cuter?

I love how comfy this plaid first Christmas outfit looks while still being super stylish!

For a classy look, a cute plaid Christmas dress like this one is perfect for a family dinner!

This baby girl Christmas outfit has just enough ruffle to be fancy while still staying simple and sweet!

For some festive flair, try this tutu set with a headband to announce that your little girl is celebrating her first Christmas!

I love the candy cane stripes on this first Christmas onesie… not to mention the matching bow!

Though newborn girls aren’t big enough to wear fancy special occasion dresses yet, you can get that same level of style with a velvet Christmas onesie like this one!

If you want an eye-catching ensemble, I don’t think you can get more festive than this cute little outfit set!

Here’s another traditional style velvet baby girl outfit that’s a little more subdued. I honestly love this color! It still feels Christmas-y without any red!

Give a little nod to old Saint Nick with this knit Christmas romper in the classic red and white. Santa hat optional!

Here’s another variation on a red sweater romper that’s a little more shapeless – and available at Target!

I think this fancy 4-piece girls’ outfit is just so pretty! It’s got a little of everything without feeling overwhelming, and those stockings are just adorable!

For a simple yet very festive approach that’s perfect for a new-newborn, this monogrammed Christmas sleeper is as practical as it is stylish!

This plaid special occasion dress is the perfect mix of traditional and modern. I love the suspenders with the cute little buttons!

Is it bad that I think this is hilarious? For some cutesy flair, this Baby Clause onesie is sure to steal the show!

Newborn Christmas Outfit Ideas for Boys

For a classic look, this red knitted jumper is the perfect ensemble for your new baby boy!

This Santa Claus outfit looks so comfy I wish they made it in adult sizes … in fact, I think every dad has a pair of pants that look like that! Aw, matching outfits for Dad and baby!

Nothing says “Christmas” quite like this candy cane-striped jumper. It just makes me think of toy stores and Santa’s workshop!

Your little reindeer will be warm and cozy in this newborn three-piece set featuring Santa’s favorite sled-pulling animal!

This plaid reindeer jumper is just glitzy enough to say “festive” while still looking very much like boys clothes! Something about that red and black plaid just looks so cozy!

Another comfy 3-piece set is this rustic Christmas outfit with cute little moose and bears on the pants and hat!

This is the perfect outfit for Santa’s little helper, but I wouldn’t expect him to start making toys anytime soon… chewing on them, maybe!

Here’s a striped baby boy Christmas outfit featuring Santa Claus… though that was an interesting choice of where to put him on the pants! Ha!

This striped jumper is very pajama-y, which I don’t mind at all. In fact, there’s a good chance your new baby boy is going to sleep through most of the festivities anyway. (Let’s hope so!)

Here’s a personalized “first Christmas” onesie that is perfect for baby boys! It also comes in toddler boy sizes, so you could easily do matching outfits for him and his big brother!

I’m detecting a pattern with these 3-piece outfits… (yes, a lot of them look similar!) but this plaid Christmas outfit was too cute to leave out!

Here’s something different: a plaid outfit with a bow tie! It’s the perfect mix of formal and casual!

With this red sleep jumper, visions of sugarplums are sure to dance in their heads (or, maybe just visions of milk… but either way, they’ll be comfortable)!

There’s something really classic about this green jumper set, and I love the plaid patches on the elbows and knees! (Plus that pom-pom… you can’t deny the pom-pom!)

Last but not least, you can’t go wrong with a Santa Clause onesie, complete with a little Santa hat!

Newborn Unisex Christmas Outfits

Nordic patterned-clothing is always a win for boys and girls! It’s festive, winter-y, and oh-so-trendy!

I think this sleeper says it all! Again, there’s just something so cozy about that red and black plaid!

This My First Christmas onesie has a neutral-enough design that I think it could work well for either a baby boy or baby girl. You could even add pants or a skirt, respectively!

Here’s another Christmas sleeper that’s perfect for any baby. Personalize the hat with your newborn’s name and you’re good to go!

Here’s another simple, cute onesie that will work for anybody!

This is such a cute outfit! I love the colors and the “merry everything” on the onesie! Like some of the other unisex options, this one comes with a beanie or a bow!

Newborn Christmas Outfits for Twins

One option that never goes out of style: red and white sleepers! I love the monogram detailing. For identical twins, this can really help distinguish them!

These adorable fleece pajamas are similar enough to look like a set but distinct enough to work for any set of twins!

I appreciate how simple and classic these adorable twin sleepers are with their matching embroidery. What more do you need for twins’ first Christmas?

This outfit set is perfect for boy/girl twins! You can personalize it with each twin’s name and add accessories as necessary!

These mix-and-match sets are ideal if you don’t want your twins (identical or not) to be in matching outfits but still want it to feel like they go together!

Who can resist the cuteness of these matching knit Santa outfits? You just know they’re going to be warm and cozy!

Why not pick up some matching Christmas sets not just for the twins, but for the whole family? Go big or go home, right?

For twin girls in particular, I think these plaid Christmas sleepers are festive but not too loud! Plus, you can personalize them!

For babies born in December, these twin coming home outfits are absolutely perfect! The red and green candy cane stripes are too cute!

Santa’s little helpers will be ready to start making those toys with these twin elf size outfits!

Last but not least, you can’t go wrong with a good pun… like these Merry Twinsmas onesies! When you have double the bundle of joy, your Christmas just gets that much better!
