Tools and materials:

  • 2 yards stretchy twinkly fabric

  • Sewing machine

Measuring the front of the shorts

1. Women’s romper sewing pattern

Start with the front of the shorts. Fold the fabric in half with right sides facing. Measure a rectangle 18 inches (length from waist to mid-thigh, or your preferred length) by 27 inches (half the hip size, plus 9 inches). Cut this piece and fold it in half.

Measuring the fabric

Measure 11 inches inwards from the fold, which is a quarter of the hip size, plus 2 inches. Draw a straight line down.

Cutting out the front of the shorts

Cut the shape and also cut the fold open so there are two pieces.

Cutting out the back of the shorts

For the back of the shorts, repeat all the same steps but make the rectangle an inch longer at the width e.g. 18 inches x 28 inches.

Pinning the front and back pieces together

2. Sew the shorts

Connect the two front pieces together and the two back pieces. 

Sewing the crotch area of the shorts

Pin the insides up to the crotch area. Sew them using a straight stitch. Once the centers are sewn, pin the side seams and crotch area, and sew with a straight stitch. 

Hemming the bottom of the romper shorts

Hem the bottom by folding it over, pinning, and sewing down.

Making the top for the romper

3. Make the top

Measure two rectangles: one for the front and the other for the back. The top is 15 inches (half the hip measurement less 3.15 inches) by 18 inches (length from shoulder to waist). Cut the fabric.

Measuring the v-neck for the romper front

Fold the fabric. From the right side, go inside 8 inches and mark. Connect that mark to the bottom left corner with a diagonal line. 

Measuring the fabric for the top front

On the open side, draw a straight line down 1¼ inches inwards. Next, measure 9 inches (length from shoulder to armpit, plus 4 inches). Draw an arc line to connect to the straight line I drew before.

Cut the front pattern. After cutting, there are 2 pieces of the front bodice top.

For the back, measure a rectangle 23 inches (half your hip measurement, plus 5 inches) by 18½ inches (shoulder to waist, plus ¾ inch). At the two sides of the rectangle, draw 2 straight lines 1¼ inches inwards.

From the top, go down 9½ inches and draw the arc line to connect to the straight line on both sides. Cut the back pattern.

At the top, go in 8 inches and mark on both right and left sides. Draw an arc to connect these two marks together for the back neckline. Cut these pieces out.

Pinning the shoulder seams ready to sew

4. Sew the shoulder seams

Lay the front pieces over the back, right sides facing together. Pin and sew the shoulder seams using a straight stitch.

Cutting out pieces for the bias tape

5. Create bias tape

Cut pieces about 1¼ inches wide for bias tape. You may need to connect these scraps together so it fits the entire neckline.

Pinning the bias tape to the romper top

Pin the bias tape to the front on the inside and sew around the entire neckline and front.

Measuring the cutting fabric for the sleeves

6. Make the sleeves

Fold a rectangle that measures from the shoulder to the wrist. My measurement was 18 inches by b17⅓ inches Cut the fabric.

Attaching the sleeves to the top

7. Attach the sleeves

Pin and sew the sleeves to the sleeve cap. The,n sew up the inner seams and side seams with right sides facing together.

Adding elastic at the sleeve cuffs

8. Add elastic to the cuffs

Make a casing for the elastic at the sleeve bottom by folding the sleeve over a bit wider than the elastic. 

Inserting the elastic into the sleeves

Pin and sew in place leaving a space in the casing. Use a safety pin to pull the elastic through. Once the edges meet, sew the elastics into a secure loop. Sew the hole closed. Adjust the fabric around the elastic to create a puffed balloon sleeve.

Connecting the DIY romper top and bottom

9. Connect the top and bottom

Pin the side seams of the shorts and the top together first. Once they are aligned, pin the rest of the garment. When sewing them together, sew ¾ inches from the edge to create a casing for the elastic at the waist. 

Making elastic casing at the waistband

Fold over the seam allowance to make the casing.

Inserting elastic into the waistband

Use a safety pin to pull the elastic through, then close up the space.
