Ever have this problem? It's the curse of an hourglass figure - 'til I get jeans to fit over my hips/butt/thighs, I end up with the inevitable gap in the back of the waistband. Not only does it give everyone a clear shot of my underoos, it's uncomfortable and breezy at best.
There's a couple of ways to fix this. One way is to add darts. If the gap is really severe, darts are probably your best bet. They can be pretty tricky though, so if the gap is a little smaller (like mine), this method works great. And it's super easy! I've even used this on trousers and skirts.
All you need it a piece of elastic, thread and a sewing machine. Basically, you're just going to use a piece of elastic to slightly gather the back of the waistband. Like every other project I've done, I didn't measure a thing for this. I just kind of figure the length of fabric that needs to be gathered and cut a piece of elastic about half to three-quarters of that length. The shorter the elastic is compared to the to-be-gathered section of waistband, the tighter the final fit will be.
Start out by pinning one end of the elastic to one end of the to-be-gathered section of the waistband and sew it in place:
Now, pin the other end of the elastic to the other end of the to-be-gathered section and sew it in place. The waistband in between the 2 ends of the elastic should be gaping:
Now, put the one end of elastic into the sewing machine and drop the needle and foot into place. Then, gently pull the elastic until the waistband is flat against it and sew along the edge of the elastic, keeping it stretched out in this position the entire time. Do the same to the other edge of the elastic. Be sure to sew both sides going in the same direction:
When you're done it should look like this on the inside:
And like this on the outside:
You can't even see the gathering once you put them on, and it works like a charm!
This particular pair of jeans stretched out a bit after wearing them, so I may end up redoing this with a shorter and wider piece of elastic for an even better fit.
