Creating darts on the skirt

1. Adjust the skirt to fit your body

Take an old midi-length skirt, turn it inside out, and put it on over your chest. Pinch the excess fabric to form darts and pin. Adjust the side seams as well.

Next, grab a marker and trace around your chest and over your hip.

2. Cut out the pattern

Take the top off, complete the tracings, then cut out your fabric. Sew along your pins and remove any excess fabric. 

Cutting out the bust pieces

3. Cut out the bust pieces

Grab a piece of plain white fabric and place your half-oval chest cut-out onto it. Use some tailor’s chalk to trace around it and cut out two matching pieces.


You can see I left a margin of a couple of inches around the cut-out. This depends on your bust size, so try to gauge the size you need by measuring your own bust.

Four fabric pieces for the bustier top

Next, cut out two more pieces in this larger size from the fabric of your skirt. Now, you have four pieces total: two for the bustier exterior and two for the lining.

4. Pin and sew the bust pieces

Place one white piece and one patterned piece on top of each other, then pin them together along two sides. Make sure you leave the peak and one side open, then sew.

Cut off around an inch of the white material from the open side.

How to make a bustier

Cut small notches in the patterned fabric - this will help the material lay flat.

Pinning the notches on the bust shape

Fold the notches in and pin them down. Sew over where you pinned. This will create a tunnel through which we will feed the elastic for the bust.

5. Add elastic to the bust pieces

Measure two elastic pieces on your chest (one for each side), just above your bust where the top of the bustier will sit, then cut to size.


Pin a safety pin to the elastic to help weave it through the tunnel of notches. Pull the elastic out on the other side and pin it at the edge. Sew where you pinned.

6. Insert the bra pads

Insert a bra pad through the peak of the chest piece, then hand sew the peak closed. 

Pinning the bust pieces to the body

7. Sew the bust pieces to the body

Turn the body of the shirt inside out and lay it flat. Place the chest pieces into the chest cutouts, wrong sides up, and pin. Sew the chest pieces in place.

Measuring the straps for the bustier

8. Measure the straps

Put the shirt on your body and grab your elastic. Measure the length of the straps by stretching the elastic over your shoulder. Cut to size.

Two rectangles of fabric

9. Cut out the fabric for the sleeves

Next, take your remaining fabric and cut it open. Cut a square, fold it over, then cut along the fold to make two rectangles. 

DIY ruffle sleeve pattern

Use some tailor’s chalk to trace out four long rectangles (two thick and two thin, to make layered ruffle sleeves) with curved bottom edges, then cut them out.

Pattern pieces

These are the shapes you should have.

Pinning the ruffle sleeves for the bustier

10. Pin and sew the ruffle sleeves

Cut small notches on the curved edge of the long strips and then pin inwards to hem. Fold the rectangle pieces in half longways, right sides touching, then pin along the longer side. Sew along all pinned areas. 

Creating the ruffles from two fabric pieces

Place two of the strips together, right sides down and one slightly on top of the other. Fold the bottom (thicker) strip over onto the top (thinner) one (that is slightly lower) and pin. Sew together. 

Sleeve pieces for the bustier top

11. Attach the sleeves to the bustier top

Turn the rectangle we sewed right side out and hand sew it to the end of the strips. Next, pin the piece of elastic for your straps to the end of the tube and slip it in.


Weave the elastic through until it comes out the other end of the long strips. These will be your sleeves. Pin them to your top (front and back) and sew them in place.

Adding corset-like structure to the bustier

12. Add structure to the bustier top

To give the bustier top some structure, stick zip ties up the bottom of it. Place a zip tie on the darts and mark where it needs to be cut.


Cut the zip tie, then sand down the end with sandpaper until it’s smooth. Sew along the darts to form tunnels, then slip the zip ties inside. Hem the bottom edge.
