Every new arrival needs a cute little romper to wriggle around in! This baby crochet romper pattern is made in one piece with no tricky stitches or shaping to worry about.
It come in sizes newborn to 12 months so you can either make it for a baby that’s about to arrive or one you haven’t gotten a present for yet!
This unisex babygrow (as we call them here in the UK) can be made for both boys and girls and styled accordingly. Although it’s great for summer and springtime, nice and breezy, you can add a warm shirt and leggings underneath for winters or a sweater on top. With a nice pair of booties and a headband, it can even be made into a set.
While I used this beautiful rainbow yarn for my crochet baby romper, you can make it in whichever color you like, solid or variegated.
More about this rainbow baby crochet romper
The pattern is worked together in one flat piece so you won’t have much seaming to do at the end (except to weave in those ends!). It might seem like there’s a lot happening in this romper but don’t worry — everything is explained in great detail to make the journey smoother for you!
Once you’re done, you can do so much with this great little baby outfit. I’ve added yellow buttons to mine and you can appliqué a character or initials on yours for personalization.
The entire romper is made with slip stitches so you won’t need to learn any difficult new technique. But if you haven’t used this method before, this is a great pattern to start with!
How do you crochet a rainbow baby romper like this?
From the front bib to the gussets, the back, and both straps, everything is worked in sequence to create the shape. This crochet baby romper is worked up with slip stitches which gives it that unique texture.
If you’re using variegated or ombré yarn, the stitch used creates a beautiful effect with different colors peeking through in each row.
Yarn
To crochet this little romper, I used the stunning West Yorkshire Spinners Colour Lab (100% wool, 100g/225m) in the color Prism Brights (894).
I really like how it made the final piece look without having to change colors at all!
According to the size you’re making, the amount of yarn used will vary between 1-2 balls of 100g yarn. The sizing chart is given below.
Yarn Substitutes
Alternatively, here are some beautiful yarns that would also work really well to crochet this baby suit:
- Swish DK by WeCrochet (100% Fine Superwash Merino Wool; 123yds/50g)
- DROPS Cotton Merino (50% fine merino, 50% Egyptian cotton; 110m/50g)
- Paintbox Yarns Simply DK (100% acrylic, 276m/100g)

Trust me, a quick peek at these notes will set you up for crochet success!
- The Front Bib and shaped Gusset are made in one piece top down. The Gusset is folded at the narrowest point and the Back is worked from the end of the Gusset with extensions on each side to make it wider.
- The centre Back is shaped. Front shaping and Straps are also worked from the top of the unworked Back piece on each side. The Straps are joined to the top Back shaping (see Diagram given below).
- The Back piece is folded around the Front so that the buttons can be secured through spaces between stitches on the Front Bib.
- Ensure buttons are stitched on securely.
- The beginning ch1 counts as the first ss and the stitch at the base of the ch-1 should be skipped. At the end of the next row, the final ss is worked into the top of this ch.
