How to sew a simple kids' dress
A child's dress is a small, fast project that teaches necklines, armholes and gathering in one go. Because children grow, the useful skill here isn't precision — it's building in room so the dress still fits next summer.
How it's constructed
- Silhouette
- A-line bodice with an optional gathered skirt
- Neckline
- Bound or faced round neck, wide enough to pull on
- Sleeves
- Sleeveless with bound armholes, or short flat-set sleeves
- Closure
- None — or two buttons at the back neck
- Hem
- Deep double hem that can be let down later
Fabrics that work
- Cotton poplin, chambray or lawn — washable and cool
- Double gauze for a soft summer dress
- Cotton jersey if you want a pull-on knit version
What you'll need
- Bias binding for the neck and armholes
- Optional two small buttons
- Matching thread
The steps, in order
- 01
Measure chest, and length from shoulder
Those two measurements decide the dress. Add generous ease at the chest — children need room to move and to grow.
- 02
Cut front, back and skirt pieces
Cut a front and back bodice, plus a skirt rectangle about one and a half times the bodice width if you want gathers.
- 03
Sew the shoulder seams
Join front to back at the shoulders, finish the allowances and press towards the back.
- 04
Bind the neckline
Apply bias binding around the neck, then understitch or edgestitch so it rolls to the inside and stays there. Check the opening fits over the child's head before you go further.
- 05
Bind the armholes
Do the same on each armhole while the side seams are still open — much easier than binding a closed circle.
- 06
Gather and attach the skirt
Gather the top of the skirt rectangle, match centres and side points to the bodice, and stitch. Press the seam down towards the skirt.
- 07
Sew the side seams in one pass
Stitch each side from the armhole down through the skirt in one continuous seam. Finish and press.
- 08
Hem deep so it can be let down
Turn a 5 cm hem rather than 1 cm. Next year you can unpick it and gain most of that length back.
Mistakes worth avoiding
A neckline that fits the pattern but not the head
Always test the bound opening over the child's head before sewing the side seams.
Binding armholes after closing the side seams
It turns an easy flat seam into an awkward circle. Bind first, close after.
A narrow hem
You lose the easiest way of getting another season out of the dress.
