Baby Kimono Onesie – Free Sewing Pattern and Tutorial

Free Baby Kimono Onesie Sewing Pattern: Make this cute kimono style onesie for your little one or as a lovely baby shower gift.

If you've ever dressed a little baby, you'll know how much they like to wiggle; making it really difficult to put any clothes on them. Any item of clothing which needs to go over the baby's head, or has lots of fiddly buttons can be especially cumbersome. That's why I love baby clothes with a front opening, such as this baby kimono onesie.

My baby girl, Umi, has been wearing a kimono as her pajamas ever since she was born. She's recently grown out of the kimono I bought for her in Japan, so I decided to make my own baby kimono in a bigger size.


The Sewing Pattern

This baby kimono onesie sewing pattern comes in two sizes, 3-6 and 6-9 months. Umi is 7 months old and she is wearing the 6-9 months size.  Make sure you print the sewing pattern WITHOUT adjusting the size. You can check if you have printed correctly by measuring the test square with a ruler.

Cut off the border and glue the 6 pages of the sewing pattern together so it looks like this:

How To Make Your Baby Kimono Onesie

Step One

Add the seam allowances as shown below before cutting the fabric. In case the diagram below is hard to read, you just need to add 1.5cm (3/5″) to all edges, except for the neckline and hem. Also cut approx. 85cm (25″) of 2cm (4/5″) wide bias tape from the same fabric.


Step Two

Cut 6 pieces of cotton tape, 18cm (7″) long each. Optional Step: You could make your own ties from your fabric, instead of using purchased cotton tape.

Step Three

With the wrong sides facing, stitch the shoulder seams together. Trim half the seam. Zigzag stitch the shoulder seam down towards the back. See Step 3 of my Baby Kimono Top sewing tutorial for photos.

Step Four

Fold sleeves twice and stitch.

Step Five

Baste cotton tape to left side seam where marked. With the right sides facing, stitch side seams 0.6mm (1/4″) from the edge. Trim close to the edge. Carefully snip seam along the curve.
Turn garment so that the wrong sides are facing each other. Stitch 0.6mm (1/4″) from the edge, encasing the raw seams.  See Step 5 of my Baby Kimono Top sewing tutorial for photos.

Step Six

Press the bias tape in half lengthways. Starting at the back of the neck, attach bias tape along the raw edge of kimono by inserting raw edge into folded bias tape. Baste stitch the bias tape by hand first, then machine stitch. Remove basting stitches.

Step Seven

Attach cotton tape to the front of kimono, where marked. Stitch a small square to hold the cotton tape in place. Stitch the free end of the cotton tape to prevent fraying.

Step Eight

Attach snap buttons where marked.

I used a soft, light denim colored knit fabric for my baby kimono. I think this would make a lovely gift, especially as a set with the baby kimono top (free sewing pattern) available for download over at my blog, Sew in Love!

This is perfect for the donations I make for the babies in the Neonatal intensive care unit. It will be much easier to run the tubes and wires through them. Thank you so very much for this pattern.
