Turning a romper into a dress is a delicate project. You must carefully remove all of the thread work that comprises the inseam of the garment. When you stitch the former legs of the garment into a skirt, you will have noticeable layering and stitching in the center of the dress in the front and back. All of the fabric once hidden in the inseam of the romper will be fully visible. For this reason, it is crucial that you take your time removing the original stitches.
Things You'll Need
Needle or sewing machine
Turn the romper inside out.
Remove all of the inseam stitching with a seam ripper. Work from the bottom hem up into the garment. The seam ripper has a bi-forcated, pointed hook on the end. Slide the point under a stitch. Pull up to break the stitch.
Lay the garment flat on an ironing board. Iron the inseam area to flatten the creases from the former folds.
Turn the romper right side out.
Lay the romper so that the front faces up. The fabric that was the inseam area of the romper should overlap on the front and back sides of the garment. Decide which piece looks better on top. Lay the fabric as you want the final dress to appear.
Pin the fabric in place with a straight pin. The material may be longer than is necessary to create a continuous skirt on the dress. Trim the excess material with scissors, then pin it in place.
Pin all the way down the garment to the bottom hem. Hold the garment up to ensure it hangs well as you pinned it. Make adjustments if necessary. Turn over the garment. Repeat the process on the back side.
Turn the dress inside out.
Sew along the straight pins to create the new seam. Sew using a needle and thread or with a sewing machine. Remove the pins as you go. Repeat the process on the other side.
