Mustard Baby Romper
Mustard yellow is such a popular color right now and I think it’s absolutely perfect for a bold and modern baby romper. This free knitting pattern contains many helpful step by step photos that will make knitting this baby romper a breeze. The design is made using garter stitch and there’s also some ribbing along the edges.
Designer: Creativa Atelier
Yarn: Garnstudio DROPS Cotton Merino (DK Weight #3)

Afternoon Playdate
This handsome fellow is looking especially dapper in his new duds. I love the sweet simplicity of his pretty blue romper. The pattern is knit using a nice thin yarn that really allows the fabric of the work to drape well and move with the baby. It is knit with stockinette stitch for the main body and rib stitch on the bib and fold up leg cuffs.
Designer: DROPS Design
Yarn: Garnstudio DROPS Flora (Light Fingering Weight #0)

Pepita
Sure, knit socks for babies are adorable, there’s no question about it. But wiggly babies are experts at losing them. That’s where the Pepita baby onesie comes in! The stretchy ribbed socks are attached to the rest of the stockinette stitch romper so there’s no chance of them falling off.
Designer: Strickmich!
Yarn: Rohrspatz & Wollmeise Pure 100% Merino Superwash (Fingering Weight #1)

Babbity Baby Romper
A basic raglan style yoke is the starting point for this dapper baby onesie in a bright and bubbly shade of blue. The stockinette stitch body is accented along the yoke, button band, and leg holes with textured garter stitch. It would be easy to add length on to the arms and legs if you would prefer a long sleeve version.
Designer: Marianna’s Lazy Daisy Days

Little Blue Dream
The baby pictured above couldn’t be cozier than in this adorable button up baby onesie complete with a snuggly rib stitch hood. He even has a little crochet friend to keep him company! My favorite part of this design is the fold up cuffs on the arms and legs because you can unfold them as the baby grows and get more wears out of it!
Designer: DROPS Design
Yarn: Garnstudio DROPS Merino Extra Fine (DK Weight #3)

Baby Fox Onesie
A bit of stranded colorwork makes a big splash on this rusty orange baby romper. All of the colorwork is on the kangaroo pocket that is attached to the front of the romper. I really like this aspect of the design because it keeps the rest of the knitting simple. It would also be easy to adapt to make other adorable animals.

Truly Wooly
I love seeing all of these adorable knitted baby onesies & rompers being modeled by all of these impossibly cute babies. Even though this model looks like he may have woken up on the wrong side of the crib, he is still so precious. The textured stitch pattern of his fashionable onesie is created using just knit and purl stitches.

Ready to Play Romper
The layering potential of short sleeve rompers is excellent for those days when you’re not sure what the weather will do next. I also like the extra layer of protection between the diaper and the handmade object that took hours and hours to make, ya know, just in case of blow outs. This adorable romper is made using stockinette, rib and seed stitches along with cables.

Squishy garter stitch and soft stripes are the hallmarks of the adorable Playdate baby onesie. It is knit double stranded in garter stitch using a soft alpaca sport weight yarn. The addition of the hood really amps up the coziness factor and adds an adorable dash of cuteness as well. Plus it has those rolled cuffs that I love!

If your little fashionista will only dress in the best, then she absolutely needs one of these Aurora Baby Girl Romper Suits. The all over lace design adds just the right amount of fanciness.
