Several reasons exist for individuals wanting to lengthen a waistband. Surgery, body shape and comfort are just a few. A common problem exists for women when the hip portion of the jeans fit correctly but the waist is too small. Lengthen the waist to correct this problem.
Things You’ll Need:
Fabric tape measure
Step 1 – Position the fabric tape measure around the waist or waistband position, whichever is appropriate for the clothing item. Measure the area. Add ¼-inch to the measurement for the seams. Mentally remember the answer.
Step 2 – Turn the clothing item inside out. Remove the stitching that connects the waistband. Remove belt loops if present.
Step 3 – Decide the width of the new waistband. Double the width and add 1 ¼-inch for the seams. Mentally remember the answer.
Step 4 – Measure, mark and cut a piece of fabric to the pre-determined measurements for the waistband. For example, the waist is 34 inches – add 1 ¼-inch for the seams for a total of 35 ¼-inch. The desired width of the waistband is 2 inches. Double the width for a total of 4, add 1 ¼-inch for a width of 5 1/4-inch. The strip of fabric required is 5 ¼-inch wide by 35 ¼-inch long.
Step 5 – Fold one long edge of the strip toward the back side of the fabric 5/8-inch. Pin in place and iron.
Step 6 – Turn the clothing item right side out. Turn the fabric so the right side or front side of the fabric is facing down. Center and pin the waistband strip to the top edge of the fabric. 5/8-inch of the waistband will extend past the front opening.
Step 7 – Sew a straight seam along the pinned area.
Step 8 – Press the seam so it points toward the top of the waistband strip.
Step 9 – Fold the top edge of the waistband strip down until the pressed edge is even with the previous seam. Pin and sew a 5/8-inch seam along the two short ends. The waistband now looks as if it was put on the clothing item backwards.
Step 10 – Turn the waistband so the right side or front side of the fabric is showing. The pressed edge is turned to the inside of the clothing item. The two end seams are encased in the waistband. Pin the pressed edge so it is even with the previous seam.
Step 11 – Line the right edge of the pressure foot up with the pressed edge of the waistband. Sew a straight seam along the edge to finish attaching it to the clothing item.
Make a button hole and attach a button, secure a snap set or trouser hook and eye to complete the waistband.
