With a subtly textured waves pattern, this crochet baby romper is a trendy one-piece outfit any little fashionista would look adorable in.
You can add a belt to it with a flower motif for extra personality or keep it as it is. Of course, since it’s handmade, you always have the option to add your little touches to it which is what sets apart your work from others. Belt or no belt, anyone who receives this romper is sure to love it!

The Summer Waves Romper is a practical garment designed for infants that can be used for a day out or photoshoot (it comes in multiple sizes). Made from soft, breathable yarn, these rompers are gentle on a baby’s skin and allow for easy movement, making them ideal for everyday wear. The one-piece design makes it easier for you to put it on anywhere, especially when baby needs a quick outfit change after a milk spill.
Personalize your crochet baby romper with different colors of yarn (maybe add an accent color) or motifs so that every baby has his or her own unique piece from you!
How to Crochet a Baby Romper
If you’re already envisioning your little one in this outfit, don’t worry about getting stuck anywhere because the construction is so easy.
You’ll start by crocheting up the crochet baby romper. It’s worked flat lengthwise, starting from the top edge to the bottom leg openings. Once the main body is ready, you’ll then seam the long edges to create a tube. This will keep your baby secure in their new romper.
After creating the leg openings, you’ll crochet a top edge ruffle and straps which bring it all together. There’s the option to add a belt and a flower motif at the end as the finishing touches.

Choosing Which Size to Crochet
I’ve given multiple sizes for you to choose from, between newborn to 24 months of age.
To choose the right size, look over the size chart below.
- The measurements given in the size chart are measured from the top edge of the romper, down around the diaper to the crotch.
- Please note this stitch pattern has A LOT of stretch to it. As you’re working it, you may feel like “it’ll never fit”, but don’t fret. The pattern is written based on the average size of each age, but it’s always best to go by the baby’s actual measurements when possible.
- The biggest piece of advice I can give you, that will make this pattern much more enjoyable, is to make sure you work your slip stitches loosely. If you do not, working the next row will be much harder than it needs to be.
Size & Yardage Chart
The notes above refer to this size chart.
Yarn
For the Summer Waves Romper, I used multiple yarns to crochet up the samples including Premier Alpaca Dance (which has been discontinued), Caron Simply Soft, and Lion Brand Wool Ease . You can use another worsted weight / 4 yarn as long as it’s similar in thickness and you match gauge.
Some great yarn substitutions are Lion Brand Basic Stitch (100% acrylic) and Lion Brand Touch of Alpaca (90% acrylic, 10% alpaca). Acrylic is generally a durable easy-care fiber that pairs well with garments.
Since this romper is very measurement-specific, it’s important to keep this in mind when selecting the yarn to crochet this up with. If you use a thicker worsted weight yarn, your romper will come out a little bigger and some stitches may not lay as nicely.

Special Stitches
- 3 DC Cluster Stitch (cluster st): yo, insert hook into designated st, yo, pull up a loop, yo, draw thru first 2 loops on hook (2 loops remaining), yo, insert hook into same st, yo, pull up a loop, yo, draw thru 2 loops on hook (3 loops remaining), yo, insert hook into same st, yo, pull up a loop, yo, draw thru 2 loops (4 loops remaining), yo, draw thru all 4 remaining loops.

Pattern Notes
- Turning chains are not included in stitch count, unless noted otherwise.
- I tend to crochet more tightly. If you normally crochet loosely, I suggest going down at least a hook size to help you hit gauge.
- The first stitch of each row is worked into the same stitch as beginning chain, unless noted otherwise.
- Yarn Notes: Premier Alpaca Dance, Caron Simply Soft, and Lion Brand Wool Ease were used for samples. You can use another worsted weight / 4 yarn as long as it’s similar in thickness and you match gauge. If you use a thicker worsted weight yarn, your romper will come out a little bigger and some stitches may not lay as nicely.
- Yarn Substitutions: Premier Alpaca Dance has been discontinued and instead, you can use Lion Brand Basic Stitch (100% acrylic) or Lion Brand Touch of Alpaca (90% acrylic, 10% alpaca) which are both worsted weight yarns.
- Yardage: Refer to the size chart above.
- I strongly suggest working a gauge swatch.
- Romper Construction: This crochet baby romper is worked flat and crocheted lengthwise from the top edge to the bottom leg openings. You’ll then seam the long edges to create a tube. After creating leg openings, you’ll crochet a top edge ruffle and straps. Lastly, you’ll crochet an optional belt.
Gauge Swatch Instructions
I strongly recommend making a gauge swatch before you begin to make crochet baby rompers.
Gauge: In stitch pattern as written in the instructions below: 11 sts = 3″; 12 rows = 3″
Note: This gauge swatch is worked in the stitch pattern that comprises the majority of the romper.
Note: This entire section is worked in Back Loops Only and the first stitch of each row is worked in the same stitch as the chain 1. Make sure to double check your ending stitch count, especially on the rows of slip stitches as it’s easy to miss a stitch or two.
Tip: The biggest piece of advice I can give you, that will make this pattern much more enjoyable, is to make sure you work your slip stitches loosely. If you do not, working the next row will be much harder than it needs to be.
Row 1: With yarn & a 6.00mm crochet hook, ch 20, sl st in the 2nd ch from your hook, sl st in each of the next 4 chs, (hdc in the next ch, cluster st in the next ch, hdc in the next ch, sl st in each of the next 4 chs) work from ( to ) twice. Turn. (19 sts)
Row 2: Ch 1, BLO sl st in each st across. Turn. (19 sts)
Row 3: Ch 1, BLO, sl st in the first st, (hdc in the next st, cluster st in the next st, hdc in the next st, sl st in each of the next 4 sts) work from ( to ) twice, hdc in the next st, cluster st in the next st, hdc in the next st, sl st in the last st. Turn. (19 sts)
Row 4: Repeat Row 2. (19 sts)
Row 5: Ch 1, BLO, sl st in each of the first 5 sts, (hdc in the next st, cluster st in next st, hdc in the next st, sl st in each of the next 4 sts) work from ( to ) twice. (19 sts)
Row 6: Repeat Row 2. (19 sts)
Rows 7 – 10: Repeat Rows 3 – 6. (19 sts)
Rows 11 – 12: Repeat Rows 3 – 4. (19 sts)
Fasten off. Your swatch should measure approximately 5.25″ W x 3″ H.

Barely There Seam – Written Instructions
Changes for sizes are written as follows: Newborn (0-3m, 3-6m, 6-12m, 12-18m, 18-24m)
Keep working yarn on the inside of the romper while seaming. With Right Side on the outside, bring Row 1 up to meet Row 47 ( 51, 55, 59, 63, 67). Sl st rows together by inserting your hook into the FLO (insert hook from front to back) of st from Row 1, then insert your hook into the BLO of a st from Row 47 ( 51, 55, 59, 63, 67) (insert hook from back to front), yo, pull thru all loops to complete sl st, repeat across. 40 ( 44, 48, 50, 52, 56) sts
Do Not Fasten Off. Continue on to legs.
Note: The seam row counts as a row in the bodice of your romper. Work into the side of the seam row just like you will for all other rows when working the legs and top edge ruffle.
Barely There Seam – Photo Tutorial
Changes for Sizes are written as follows: Newborn (0-3m, 3-6m, 6-12m, 12-18m, 18-24m)
The most important part of creating this seam is your hook placement. Read the instructions carefully and take a moment to identify each loop before starting. Once you work the first one properly, the rest are a piece of cake… or pie… or whatever suits your fancy.
Photo B: Insert your hook into the BLO of a st from Row 47 ( 51, 55, 59, 63, 67) (insert hook from back to front).
Photo C: Yarn over, pull thru all loops to complete sl st, repeat across. 40 ( 44, 48, 50, 52, 56) sts
Finishing (All Sizes)
Changes for sizes are written as follows: Newborn (0-3m, 3-6m, 6-12m, 12-18m, 18-24m)
Attach Straps: Using a yarn needle and piece of yarn, sew the ends of the left & right shoulder straps (that have the stitch marker), to the front inside of romper. Attach the straps 2.5″ ( 2.75″, 3″, 3.25″, 3.5″, 3.75″) apart.
Attach Buttons: Position the buttons 2.25″ ( 2.50″, 2.75″, 3″, 3.25″, 3.50″) apart, on the inside of the back of the romper. Using a needle and thread, sew the buttons on to the inside of the back of the romper.
Belt and slide are both optional. You can work a longer belt (as written) and tie it in a bow if you prefer, or you can use a simple thin chain and tie it in a bow.
Attach Belt: Wrap belt around the bodice of the romper. Either add a slide or tie the romper how you’d like it. Position the tied belt where you’d like it (I prefer it off to one side). Using a yarn needle and piece of yarn, tack stitch the belt at each side of the romper.
