How To Make Regular Pants In Maternity Pants

Maternity clothing helps you to be comfortable and look professional as your body changes during pregnancy. Maternity pants usually have mesh or stretch fabric over the belly so that they expand as your stomach grows. It can be difficult to find maternity pants that fit well into the hips, buttocks and thighs as well as the stomach. One way to ensure that your maternity pants fit is to convert normal pants into maternity pants.

If you do not have the pants at home that you want to convert, then go to a thrift store and try on jeans or pants. You will spend less and find pants that have already been worn and if stretched a bit. Learn how to make regular pants in maternity pants.


Method 1 of 3: Cut Your Pants


Try on the jeans or pants you want to wear. Zip them to the point where they can comfortably close without pinching your tummy.

Mark this point in front of your pants with a fabric pen.


Draw a curve that dives from just under your belt side ties to the point marked on your zipper. You should have a very smooth curve that can cut through your front pockets.


Cut along the curve with a pair of fabric scissors, once you are satisfied that the curve is even on both sides.

Referring to Fig.

Cut all around the pants, just under the tabs. Your back pockets, if you have them, should remain intact.


Ready sewing machine to sew your logo just below the cut you just made. This will prevent wear and tear. Put some thread that is the same color as your pants.


If you are converting jeans, then consider using a needle size 100 jeans and a very strong thread. Some handicraft stores sell thread that is specially made for denim sewing.

  • Referring to Fig.

Sew once along the entire edge of the cut using a straight stitch.Then stitch over 1 hour around the zipper and fly region.

Method 2 of 3: Create Your Waist

Maternity Band


Cut a long elastic band. You should wear elastic that is 2 inches (5 cm) or wider so that it does not dig into your belly.

Try on the pants again. Wrap the elastic around your waist, at the top edge of your pants, where they meet your pelvic bones. Mark a length over the band that is comfortable and not too tight.

  • Remember that you want the elastic to be tight enough to keep the pants on, but also allow a little room for growth.


Pin the elastic together at the point where you marked with your fabric pen. Cut off any excess elastic excess. Sew the ends of the elastic together.

  • 4

Choose a 4-way stretch knit fabric or tight t-shirt to wear to the section of the bands that fit over your stomach. You may want to choose black, blue or other color to match your pants or a printed fabric that will create some attractive contrast.

  • You will need at least 1/4 of a yard for the fabric waistband. A Lycra / cotton blend will work well.
  • If buying a length of knit fabric, ensure that it is quite elastic, so that it does not stretch too far. If you choose a t-shirt, find one that fits comfortably on your tummy. You can cut a horizontal section of the shirt to use as your waist band.

Referring to Fig.

Measure your elastic with a woven metric tape. Subtract 2 inches (5 cm) from this measurement. This is your wide measurement for your waist band fabric.


Cut a length of knit or t-shirt material that is equal to the width measure. Cut it so that it is between 14 and 17 inches (35.6 to 43.2 cm) in height. If you have a short trunk, choose a 14-inch (35.6-centimeter) measurement, and use a longer measurement if you have a long trunk.


Pin the ends of the fabric together to form a loop, as if you are trying to make a top of the tube. Sew the side together in your sewing machine.

Referring to Fig.

Fold the fabric tube in half so the verses are ringing. The new seam should be folded in half and you should have both edges at the bottom and the fold at the top.

Referring to Fig.

Measure a wrapper for your elastic. Depending on the width of your elastic band, you will need to measure the width, more than 5/8 inches (1.6 cm). For example, if you have a 2 inch (5 cm) elastic band, then measure 2 and 5/8 inches (6.6 cm) above the rough edge.


Mark the measurement with a fabric pen or a piece of chalk. Mark the measurement around the entire fabric cycle.


Sew along this line using a zigzag stitch. This will allow you to stretch the fabric when you pull the pants on and off. You want to sew between 2 layers of folded fabric, but be sure to sew through both sides of the loop.


Insert your elastic loop into the bottom of the fabric loop. It should stop at the thread that has just sewn.

A seam just below the elastic band around the entire tube.Use a zig zag point again.This will close your case to the elastic.

Method 3 of 3: Sewing Your Maternity Pants


Put your pants on a table. Fold the fabric loop so that it is from the inside out. Pull it over the top of the pants until the edges of the fabric tube and the pants meet.


Pin the lips together. The right, on the outside, the sides should be ringing.


Make a seam through the fabric and the pants on the top twice. Use a narrow zig zag stitch. You can also choose to Serge the final seam, to avoid wear.


Unfold the fabric and try on your homemade maternity pants. You either can use them with the tissue tube that extends up to your belly or with it folded in half.


Keep in mind that these changes in your pants are permanent. You can not undo the conversion at a later date. Choose pants that are cheap or that you know you will not want to wear after your pregnancy.
