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.

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.

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.
