A simple sewing project with a Peter Pan collar, lace trim and a fabric full of stories.

A shirt that once travelled through long days, commutes or celebrations doesn’t have to disappear into the back of the wardrobe. It can keep on living – in a new form. In this tutorial, I’ll show you how to turn an old men’s shirt into a lovingly sewn kids dress – with a Peter Pan collar, delicate lace trim and little buttons that give the dress its own character.

You don’t need a complicated pattern or a perfect studio. With a bit of time, calm and joy in making, something unique appears under your hands – a piece that quietly carries stories. A little dress that gently accompanies everyday life and reminds you of the magic hiding in small things.

Why this upcycled kids dress brings so much joy

A men’s shirt already brings a lot with it: a finished button placket, soft worn-in fabric, and tiny details like cuffs or a breast pocket. You’re not only working in a more sustainable way, you’re also using materials that feel good on the skin and are often easier to sew than completely new fabric.

Instead of giving away something that once mattered, you turn it into a new favourite piece for small people and big adventures. “Old” naturally becomes “precious” again – and you give a garment a second life, close to the skin once more.

Upcycling is more than just DIY: It means appreciating resources and being more mindful with what we have. An old men's shirt that may have stains or small holes can be turned into a favorite piece for children with a little imagination and skill. This DIY project invites you not only to be creative, but also to feel gratitude for the things around you.

Materials for your upcycled kids dress

You will need:

one large, old men’s shirt (ideally cotton)
sewing machine and matching thread
fabric scissors
tailor’s chalk or fabric marker
pins or fabric clips
iron
lace trim
3–5 buttons of your choice
optional: ready-made bias tape or fabric strips from the shirt to make your own bias binding

If you like, you can place a well-fitting kids dress next to your work. It helps you get a feeling for the proportions and gently adapt the shape to your child.

Step-by-step tutorial: sewing a kids dress from a men’s shirt

1. Preparing the shirt

Take a calm look at the shirt. Are there any stains, thin spots or small flaws you’d like to avoid later? Iron the fabric until it’s smooth – this makes cutting much easier and keeps the pieces from shifting while you work.

Then roughly cut the front and back apart. Keep the sleeves and other larger sections – you’ll use them later for the sleeves and the Peter Pan collar.

2. Cutting out the pattern pieces

Front piece: Use the front of the shirt with the original button placket as the front of the dress. This way, you keep a lovely detail and don’t need to insert a zip.
Back piece: Cut a back piece in a similar width; you can keep the neckline slightly higher and adjust it later.
Sleeves: Cut four sleeve pieces – two mirrored pairs so you can create two finished sleeves.
Peter Pan collar: Cut four small rounded “half-moon” pieces that will be sewn together in pairs.
Bias tape: If you don’t have any at home, cut long strips at a 45-degree angle to the grain line from the shirt fabric. This makes them more flexible and lets them curve neatly around necklines and armholes.

If you use a kids dress as a template, lay it loosely on the fabric and add a little seam allowance all around. This way you follow a shape that you already know fits your child.

You can get a feeling for the overall pattern from the photo and adapt it to your child’s size.

3. Sewing the Peter Pan collar

Place two collar pieces right sides together. If you’d like, tuck the lace trim between the two layers so that it peeks out softly along the edge later.
Stitch along the rounded edge with care, then turn the collar right side out and press it flat with the iron. This creates the soft, classic shape that will give the dress its gentle, almost fairy-tale expression.

4. Preparing the sleeves

Place two sleeve pieces right sides together and sew along the outer edges. If you wish, add lace trim at the hem before turning the edge up and topstitching it in place.
Turn the sleeves right side out and press them.Well-pressed pieces are easier to handle in the next steps – the seams lie flat and you can insert the sleeve more precisely.

5. Sewing the dress body

Place the front and back pieces right sides together.
First close the shoulder seams, then the side seams.
Neaten all open edges (for example with a zig-zag stitch or an overlock) so that the inside of the dress feels just as calm and tidy as the outside.

After this step, you can already see clearly how the shirt slowly turns into a dress.

6. Inserting the sleeves

Now it’s time to insert the sleeves:

Turn the dress wrong side out and the sleeves right side out.
Slip each sleeve into the armhole, right sides facing.
Mark the top centre of the sleeve and pin it to the shoulder seam so the curve is distributed evenly.
Pin from there towards the front and back until the sleeve fits nicely into the armhole.

Sew the sleeve all the way around and neaten the seam allowances.Make sure nothing pulls or puckers – if you sew slowly, you’ll feel immediately where the fabric still wants a little more space.

7. Attaching the collar and finishing the edges

Now the Peter Pan collar finds its place:

Lay the collar pieces around the neckline so that they meet softly at the front.
Pin them in place and sew them on with a straight stitch.

8. Finishing neckline and armholes with bias tape

For this step, you’ll use your prepared bias tape:

Place the tape, as shown in the photos, along the neckline, right sides together. Sew it in place with a straight stitch.
Fold the tape over the seam allowance to the inside and topstitch it from the right side, enclosing the raw edge.
Repeat the same process along the armholes (where the sleeves are joined to the dress) so that no raw seams are left exposed.

The bias binding gives you stable, clean edges and protects the fabric from fraying. At the same time, it feels soft at the neck and arms, which is especially nice for sensitive children’s skin. This gives you a neat, almost “tailor-made” finish – the dress looks carefully sewn and feels gentle against the skin.

9. Sewing on the buttons and finishing the dress

Now only the small details are missing:

Choose buttons that you love – maybe you keep the original shirt buttons, or maybe you add a new pop of colour.
Sew them on securely and try out how many buttons you want to close or leave open so that the dress is easy to put on and take off.

Finally, give the entire dress a thorough press. Now you can hold your work in your hands – a dress that gently connects past and present.

A quiet ending

Maybe this shirt was once there for important moments – in everyday life, at celebrations, on journeys. Now it can begin a new chapter, close to a child who will play, dream and grow in it.

That is where the magic of making things yourself lives: things are allowed to stay, just in a different form.

If you’ve discovered joy in sewing and transforming garments, you can turn more pieces into small everyday wonders – step by step, in your own rhythm.
