Let Out Waist in Mens Dress Pants
Altering mens dress pants is one of the easiest alterations you can do. The center back seam is constructed so that it can be adjusted.. Usually there is a center back seam in the waistband also, which makes letting out or taking in a pretty basic alteration. Follow along as I demonstrate the details of this simple alteration.
A Note About Terms I've Used ...
There are not too many technical words associated with learning how to let out pants. It may help you to know these terms, though...
Center Back Seam is the seam that goes from the seat, up the back side to the waistband. In mens pants, it usually extends into the waistband also.
Waistband is the band (usually 1½" or so)that attaches to the body of the pants. It includes a closure, such as a hook and eye or button in the front.
Here's What You'll Need ...
|Scissors||Heavy Duty Needle||Ruler|
Chart One: Rip Old Stitching and Replace with New Seam
|STEP ONE: OBSERVE|
Here is the inside of the waistband of the mens dress pants I am going to let out. Part of the beltloop has already been removed. The white edge is a seam finish you find on some pants.
|STEP TWOHere you see the outside view of the pants. The beltloop stitches have been removed at the bottom. Now it is time to remove the stitching that attaches it to the pants. Remove all broken threads too.|
|STEP THREENow you can open up the waistband completely. This enables you to see how much leftover seam allowance there is on the inside of the waistband. Mens dress pants usually have a generous seam allowance in the center back. |
Time to mark your new stitch line. I use a ruler and a line of pins to mark. You may want to use tailors chalk or a marking pen.
|STEP FIVEAlthough this step can be done before Step 4, I listed it here because it is a form of a double check. You must make sure the horizontal seam that connects the waistband to the pants is matched up before you sew.|
|STEP SIXYou can see here that the seam allowance on mens dress pants is often quite a lot. That makes it critical that you line this seam up. Use this photo as a guide and then pin into place. You want to see results like the photo in Step 10.|
Using a heavy duty needle, stitch along the markings that you made in Step 4. My markings are pins, Yours may be basting stitches, a chalkline or marker lines. Taper into the existing seamline.
|STEP EIGHTHere you can see the new seam line and the old one. Notice that when I tapered the new stitching into the old that I did it very gradually. This will prevent you from getting an embarrassing bubble in the seat.|
|STEP NINEThe tapering of the seamline shows very well in this close up view. The more you let out the seam, the longer you have to make your new seamline, in order to taper it properly. Remove the original stitch line and pick out the threads.|
|STEP TENThe right side of the mens dress pants should look like this. See how one side of the horizontal seam is exactly matched to the other at the center? This attention to detail will show that you are a professional.|
