The onesie is perhaps the cutest outfit you can dress up your toddlers in.

Unfortunately, The Sims 4 includes very few onesie designs in the original game (or even in the expansion packs). Which is a pity since they’re so darn cute!

But we’ve scoured the web and found a selection of the best custom onesies made by the CC community – all ready to dress up your Sims children in style, whether they’re chilling out at home over the weekend, or settled down for an afternoon nap.

And this CC is available for both male and female toddler Sims, with its own original mesh (editable if you know how!)

But best of all:

This CC is completely base game compatible, so you can dress your toddlers up in this new style from day one.

If your kids love a good animal onesie, look no further than this CC from Simmer ooobsooo.

As a mesh edit from an original mesh for adults by Imadako, this onesie design truly feels unique. And it’s available for both boys and girls.

There’s 24 different color swatches and 5 meshes to choose from here too. So your child Sims can decide whether to dress as a penguin, cat, teddy bear, bunny, or even a frog (among many other options!)

If you look closely, you can see there’s even a cute tail included on some of the meshes.

That’s what I call craftsmanship.

For even more onesie choices, Redhead Sims has designed this fantastic CC adapted from the original TS3 mesh by plumb-da-bots.

It’s available as a unisex onesie for toddlers, and you can choose from any of the 6 unique designs based on popular kid’s TV shows and movies.

The most interesting designs include Stitch, Pikachu, or the Cookie Monster.

Or if you’d rather stick to the basics, pick a sweet cow patterned design – or maybe an adorable blue unicorn. Great for boys or girls!

This male toddler onesie CC has popping designs galore!

It’s an original mesh by McLayneSims, and this CC was made for male toddler Sims specifically.

It offers a selection of 12 different swatches, from plain color swatches, to tiger stripes, to full-blown dinosaur dress-up looks, complete with a cute dinosaur hat and everything.

We even spotted a cute design inspired by Sully from Monsters Inc.

If the festive season is right around the corner for your Sims, then there’s no better outfit for your toddlers than this cute Christmas elf onesie from InfinitePlumbobs.

The good news is that you can select this outfit for both male and female toddlers as a unisex design.

The bad news is… well, there is none. Just more good news.

Since this is a base game recolor, the outfit is totally base game compatible.

That said, it may tie in best if you have the free Holiday Celebration pack installed through Origin (or perhaps the Seasons expansion pack if you want the full winter holiday experience!)

Either way, you’ll be able to capture some adorable posed pictures on Christmas morning.
