Seashell Baby Crochet Leggings – Free Pattern

by Doroteja

This was my very first time writing a pattern for crochet baby leggings. I am obsessed with a shell stitch lately, and I am implementing it everywhere. In fact, I’ve shared a couple of designs already in the past. Some of them are SeaShell Baby Bonnet, Peony Twirl Dress, or rompers Little Dreamer and Button n Braces.

Days are getting shorter and much colder. The Autumn is in its full swing and we might even get some snow this year. Who knows. The Winters aren’t what they use to be. Nowadays, we get very little or almost no snow. When I was a child, Christmas was always white and we were constantly playing outside in the snow, building a snowman, igloos or were sledding down the heel. Memories!

Colder days ask for more cozy and warm clothes. Such as hats, cardigans and shawls. You will see more patterns for those in the near future. With all of this in mind, after all, winter is coming, I’ve designed a pattern for crochet baby leggings or pants.

As always, I was using 100% cotton yarn. It’s my yarn of choice because it’s easy to work with, it’s available in many beautiful colors and it’s anti-allergic (plant-based). It means it doesn’t irritate the skin, which is the most important factor for me when it comes to crocheting for babies. Cotton is great for any time of the year.

However, if you would like to make it softer and even warmer, try to use beautiful merino or synthetic yarn. Those are great choices too. The merino yarn is an animal-based fiber. It has a gorgeous texture, and there is a very thin chance for anyone to be allergic to merino wool. It’s super soft and cozy, perfect for babies.

I am not the biggest fan when it comes to synthetic fibers. They are man-made and not very breathable. But hey, synthetic yarn can be great too.

Synthetic fibers are available in many beautiful colors, usually very affordable and very easy to work with. The fibers are nicely twisted together, and you can pretty easily pick them up with a crochet hook. No matter how pointy crochet hook you have. Therefore they are perfect for first-time crocheters and knitters.

Crochet Baby Leggings – Seashell

The pattern for crochet baby leggings is written in 3 simple steps: 

  • Ribbings – an area around the waist,
  • Middle part – the segments between the ribbing and the legs
  • Legs – part that will cover the leg area.

Please, read the instructions carefully. Don’t skip any parts of the pattern and make sure you are not accidentally losing or adding additional stitches to the pattern. That might affect the final look of your design.


Take some yarn of your choice and a 4.0 mm crochet hook. Create a foundation chain made of 8 chains.

Start in the 2nd chain from the hook. Work in rows. After each row create a turning chain and turn the row.

Work your first row into back bumps of the foundation chain.

Row 1: Work 1 sc into each of next 7 chains. = 7 sts.

Work the following rows into back loops only. Make sure your stitches are nice and tight.

Row 2 – 70: Ch 1. Work 1 sc into each of next 7 chains. = 7 sts.

Ch 1. Join both ends of the ribbing together with a few simple slip stitches. Ss 7.

Do not cut and fasten off just yet. 

Middle Part

Continue with the same strand of yarn. From now on work in rounds.

After each round, join the round with a slip stitch made into the first stitch of the round. After that, create a turning chain and turn the round.

Round 1: Ch 1. Work 1 sc into each row on the ribbing, 70 in total. Ss. = 70 sts.

Round 2 – 8: Ch 1. Work 1 dc into each of next 15 sts. CL. Dc 30. CL. Dc 15. Ss. = 70 sts.

Cut the yarn and fasten off. Continue with the legs.


The seam of slip stitches indicates the backside of the pants. 

Take 4 stitch markers. Place the first two; one on each side of the slip stitch on the backside of the pants (photo 1). Skip the slip stitch that is in between those two stitches! Place the other two right in the center of 30 (36) sts on the front side of the pants.


Insert the crochet hook into one of the stitches marked with a stitch marker and start crocheting towards the maker that is father away. 

The following segment is made in rounds. After each round, create a foundation chain and turn the round.  

Row 1: Ch 2. Start in the same st. Work 1 dc into each of next 15 sts. CL. Dc 15. Create the last dc st of the round through both stitches the last and the first stitch of the round at the same time (photos 5 and 6). Ss. = 35 sts.

Row 2: Ch 2. Dc2tog. Dc 13. CL. Dc 13. Dc2tog. Ss. = 33 sts.

Row 3: Ch 2. Work 1 dc into each of next 14 sts. CL. Dc 14. Ss. = 33 sts.

Row 4: Ch 2. Dc2tog. Dc 12. CL. Dc 12. Dc2tog. Ss. = 31 sts.

Row 5: Ch 2. Dc 13 sts. CL. Dc 13. Ss. = 31 sts.

Row 6: Ch 2. Dc2tog. Dc 11. CL. Dc 11. Dc2tog. Ss. = 29 sts. 

Row 7: Ch 2. Dc2tog. Dc 10. CL. Dc 10. Dc2tog. Ss. = 27 sts.

Cut the yarn and fasten off.

Repeat all the steps for the second leg.

And that is the finished look of your leggings. I think they look adorable! The shell stitch on the sided makes them extra cute and girly.

If you would like to make a pair for a boy, skip the CL stitch and work five dc stitches instead. Instead of making two double crochet stitches, one chain and two double crochet stitches again into one stitch, try creating just one double crochet into each stitch to the row below. It’s super easy!

As you might know, I am always very happy to see your creations when you try out my patterns. I am curious to know more about the yarn you chose, crochet hook you were using and of course if you added of had to skip something in the pattern to tailor it to your liking.

Hello would like to say really love the things u make. But i have a hard time with your patterns as they don’t state how many stitches u should have at the end of each round. This really helps newbies to stay on track.

Hi Collette! The number at the end of the row after the sigh = is the number of stitches you have to have when you finish the row/round. 🙂
