Elastic Seams are perfect to use for dresses and rompers. In this Sewing 101 video tutorial you'll learn how to add seam-enclosed and exposed elastic waist seams to your garments!
Supplies we used for this tutorial:
Seam-Enclosed Elastic Waist Seams
The seam-enclosed variation is very common and offers a lot of comfort!
Start by joining the bodice and skirt piece with a 5/8” seam allowance. Attach a strip of elastic on the underside the seam by using a zig zag stitch. A little tip we like to use is cutting the elastic with an additional 2”, so that it stretch consistent all the way around the waistband, and no pre-joining elastic is required.
Next lay the seam allowance down, toward the skirt. Top stitch 3/8” around to enclose the elastic and secure the seam allowance. Sewing the waistband down on the skirt piece instead of the bodice piece gives much less risk for popping the topstitch, since the bodice is usually more form fitting than the skirt piece.
Exposed Elastic Waist Seams
Exposed elastic waist seams are very common as well, and give a cleaner look. It requires less steps, but a tad more precision.
Start by combining the bodice and skirt piece with a ¼” seam allowance. Attach the ¼” elastic strip with a zig zag stitch.
When you sew the zig zag stitch- position it so that one point of the zig zag overedges the elastic, and the other point penetrates the elastic and meets the seam at the same time.
Having that little edge of fabric left on the seam allowance adds as a buffer between the elastic band edge and your skin, for a more comfortable fit. Otherwise an exposed elastic seam can be a little itchy.
