I’m sort of frugal about buying clothes already, so buying maternity clothes is a whole new kind of challenge. I like clothes, and I like buying clothes, but it’s more fun when you can afford and find what you want. It turns out that maternity clothes are really expensive and harder to find. I have had a lot of luck at maternity consignment shops, and the sale rack at Target. The pickings are slim and it’s hard to find things I like in the right size.
So when I did find these maternity jeans in my size for a really good price I didn’t hesitate much. The are low rise with elastic in the waistband, and I could wear them early on when my other pants started getting to tight. I had to wear one of those belly bands too since they were too big at the beginning. My hope was that the cut would allow me to be able to wear them for a long time since the belly goes over the waistband and they would stretch to fit better as I got bigger.

Me in the jeans around 23 weeks. They look like they fit well, but fall down when I’m walking around.
Turns out that as I got bigger they actually continued to sag (and by this time I was done with having to readjust the stupid belly band all the time. Since the pants are low rise it’s hard for the bellyband to stay in place when I sit down and stand up). So I decided that they would be more comfortable and fit better if there was more support in the form of a stretchy band like typical maternity pants.
The fabric store has a number of different strengths and widths of elastic, but I decided on a stretchy knit since the elastic was scratchy on the edges and would need to be encased in a band of fabric anyway. Here’s my process for adding a band into the pants.

1. Cut fabric to make a double thick band about the size of waist, minus an inch or so for some stretch, plus seam allowance. I made mine about 5.5″ high when doubled over to account for the seam allowance of stitching it into the pants. This would vary depending on how high you want the band to be over your belly and where it will be stitched into the pants.

These are the zigzag stitches on my machine. The one on the left is the typical back and forth zigzag, and the one on the right is a line a small stitches that travels in a zigzag path. I decided to use the one on the right for this project as it seems that the stitches are stronger.

2. Stitch the short side of the band together.

3. Fold back into a double thick band and stitch the two layers at the bottom together for a “finished” edge (this is as finished as I could think of for sewing without a serger).

This is my finished edge at the bottom.

4. Pin band into pants and hand stitch into the seam of the waist band of the pants.

Wah-lah! All stitched in. You could also sew in a pretty ribbon over the edge of the band for a more finished look and to conceal the blue stitching, but that sounded like a lot of work.

The finished product and with the band folded over on the right for a shorter rise. I think my only advise is to make sure that the band is smaller than your waist (remember that the fabric may stretch even more with wear in between washings too) so that it isn’t too big and bulky under your shirt. Since I did this at 23 weeks I assumed that there would be more belly girth in the coming weeks/ months to fill it out too. I was very pleased with the new band and they are certainly more comfortable to wear and don’t sag.
Unfortunately, we had a week of over 100 degree weather when I wasn’t wearing jeans, in fact I was trying not to wear pants at all if I could help it, and now at close to 26 weeks the jeans are feeling a bit tight in the legs. I was hoping that I wouldn’t gain too much weight in my butt/hips, not because of vanity or fear of gaining pregnancy fat, but because I don’t want to have to find new pants that fit.
The sewing actually wasn’t very difficult and the most time was spend hand stitching while watching a movie, so even if I can’t wear them to full term it was still worth the work. There is always that postpartum period where maternity clothes are still necessary too.
