Jumpsuits have been popular throughout the years, but they have become even more fashionable in recent years. Some celebrities have even worn jumpsuits on the red carpet. If you have been wanting to try this look, but not willing to pay the high prices for designer jumpsuits, then you can always make your own jumpsuit. Making your own jumpsuit is quick, it does not require a pattern, and you can make one for the cost of your fabric alone.

Part 1

Part 1 of 5:

Cutting the Fabric

1
Gather your materials. Creating a jumpsuit is a pretty easy project, but you will need some special items. Before you begin, you will need:^{[1]

- a pair of loose-fitting sweatpants
- a loose fitting tank top
- some stretchy jersey or comparable fabric in the print or color of your choice
- a pair of sharp scissors
- pins
- a sewing machine
2
Consider using a pair of old pajama pants for the bottoms. If you do not want to make pants, then you can also use a pair of old pajama bottoms for the pant bottoms of your jumpsuit. Then, all you will have to do is create a matching top and add the top to the pants.^{[2]

Research source}
- Choose a fabric color and type that matches your pajama bottoms. For example, if the pajama bottoms are navy blue and made of a jersey material, then select a similar navy blue jersey material for the top. Or, if the pajama bottoms feature a print, choose a solid in the dominant color of the print, such as red if the print is mostly red.
- If you want to, you can also buy a jumpsuit pattern, then use your body measurements to create the design.^{[3]

Lay out your fabric and sweatpants. Fold your fabric in half so that the print is facing in. Then, lay the fabric on a hard, clean surface, such as a large table or on the floor (as long as it is clean). Smooth out the fabric so that there are no ripples.^{[4]

Research source}
- Then, place your sweatpants on top of the fabric. There is no pattern for this project, but you can use your sweatpants to help you make the jumpsuit in the right size.
- Fold the sweatpants in half so that the legs are lined up with each other. Then, lay the pants on top of your folded fabric. The waistband of the pants should be near the folded edge and the inseam of the pants should be facing out towards the outer edge of the fabric.
4
Cut the fabric. The sweatpants will help you to create a loose fitting pair of pants for the bottom half of your jumpsuit. Cut the fabric in a straight line on the outer edge of your sweatpants. You will want your pants to narrow towards the bottom, so move the sweatpants aside.^{[5]
X
Research source}
- After you have finished cutting the basic pattern, pick up your sweatpants and set them aside.
5
Trim ½” off of the curve. The curved edge is where the waistband will be, so you will need this area to be slightly snug. Trim along this curved edge on both sides. You will need to trim off about ½ of an inch or 1½ centimeters.^{[6]

Part 2 of 5:

Sewing the Waist and Inseam

1
Pin the edges. You will need to pin the curved edges in place first. These edges will make up the hip and waist area of your pants. Make sure that the fabric edges are even and place a pin every few inches.^{[7]
X
Research source}
- When you are pinning the fabric, insert the ball-head pins into the fabric from the outer edge and moving in towards the center, not parallel with the edge.^{[8]

2
Sew the curved edges. Begin sewing the fabric pieces together along the curved edges that you just pinned together. Do not sew any of the other edges yet. Remove the pins from the fabric right before you sew over them.^{[9]

- Make sure that your stitches are about ½ of an inch (or 1 ½ cm) away from the edges of the fabric. This will help to create a strong seam.
- After you have finished sewing, trim off any excess thread from the areas you just sewed.
3
Adjust your fabric. After you have sewed the curved edges together, pick up your fabric and fan it out. Then realign the fabric so that the two seams you just sewed are facing each other. Then, lay your fabric out on a flat, clean surface again.^{[11]

Research source}
- The finished product should look like a pair of pants minus the inseam stitches. You will need to sew this inseam next to complete the pants.
4
Pin and sew the inseam. Place one pin at the crotch and then continue placing pins along the inside of each of the pant legs. Position the pins so that they are about three inches apart. Make sure that the pins are about ½ of an inch (or 1 ½ cm) from the edges of the fabric.^{[12]

- After you have finished pinning the inseams, sew along the edges and remove the pins as you go.

Part 3 of 5:

Adding the Waistband

1
Try on your pants. To determine where to place your waistband, you will need to turn the pants inside out and try them on. You should have a large flap at the top of the pants. Pull this fabric up and then fold it over all around the waistband so that the top fold is sitting at your natural waist (or wherever you like your pants to begin).^{[13]
X
Research source}
- Try to make the fold as even as possible all the way around.
- When you find a comfortable height for the waistband, you can take off the pants. However, remove the pants carefully to keep the waistband folded how you like it. You can also place a few pins to secure the waistband.
2
Trim off the waistband material and flip it inside out. Use your scissors to trim along the bottom edges of where the folded material ends. This will seem low, but you will be adding this material back onto the pants, so don’t worry. Then, take the waistband material that you just trimmed off and reverse it. Flip the material so the print side of the material is facing out instead of turned in.^{[14]
X
Research source}
- The waistband should be doubled and the print side should be facing out on both side.
- Make sure that all of the edges are even.
3
Pin the waistband onto the pants. Hold the waistband material next to the waistline of the pants so that the top fold is facing downwards in the direction of the pant legs. Then, pull the waist of the pants through the waistband and line up the edges of the waistline with the rough edges of the waistband.^{[15]
X
Research source}
- Pin the edges together. Make sure that the pins go through all of the material layers.
4
Sew along the pinned area. Once the waistband is pinned in place, sew along the edges. Sew the stitch about ½ of an inch (or 1 ½ cm) away from the edge to create a strong seam. Pull the material taut as you sew to ensure that the waistband will not have any bumps or ripples.^{[16]

- Pull out the pins as you go and set them aside.

Part 4 of 5:

Making and Attaching the Top

1
Double up the material and position the tank top. Get a large piece of the same material you used for the pants or two smaller pieces and lay them so that the print sides are facing each other. Then, place your tank top on the two layers of material.^{[17]
X
Research source}
- There is no pattern for the top, but the tank top will help you to cut the material in the right size and shape.
2
Cut along the edges of the tank top. Using your scissors, cut along the outer edges of the tank top. Follow the lines of the tank top and try to make the lines as straight an even as possible. Follow the curves of the armholes and neckline as well.^{[18]
X
Research source}
- When you are done, you will have two tank top pieces.
- Keep in mind that you can make the neckline as deep or as high as you want it to be. You can also use any style for the neckline that you want. For example, you could do a scoop neck, a V-neck, or a square neck.
3
Hem the edges of the tank top neck and armholes. Start by pinning along the edges of the armholes and neckline for the hem. You will need to hem the neckline and armholes twice. Fold over about ½ of an inch (or 1 ½ cm) of material once, then pin it into place and sew along these lines.^{[19]
X
Research source}
- Then, remove the pins and fold over the material to create another ½ of an inch (or 1 ½ cm) hem.
- Pin and sew this hem as well.
4
Pin and sew the sides and shoulders of the tank top. Next, with the two tank top pieces facing each other, line up the edges. Pin along the sides of the tank top and the shoulders. Then, sew these areas together about ½ of an inch (or 1 ½ cm) from the edge.^{[20]
X
Research source}
- Remove the pins as you go.
5
Attach the tank top to the pants. With your pants still right side out and the tank top inside out, slide the pant waistband through the neck of the tank top. Then, continue to slide the pants through the tank top until the top of the waistband is lined up with the bottom of the tank top. Then, pin these edges together and then sew them together.^{[21]
X
Research source}
- If you are using old pajama bottoms for your jumpsuit instead of pants that you made, then you can follow the same process for attaching the tank top to the pajama bottoms. Just make sure that the bottom of your tank top matches up with the top of the elastic waistband on your pajama pants.^{[22]
  X
  Research source}
- As you sew along the edges of the tank top bottom and waistband top, pull the materials taut. This will help to ensure an even seam. It is also necessary because the tank top will be slightly larger than the waistband.

Part 5 of 5:

Wearing Your Jumpsuit

1
Define your waist with a belt. Jumpsuits are often baggy around the waist, which can be unflattering. Defining your waist with a belt is a great option.^{[23]
X
Research source}
- Try a wide band stretchy belt or a thin fitted belt.
2
Add something to break up the look. A jumpsuit can be a little overwhelming, especially if your jumpsuit is in a bold print, so you may want to find ways to break up the pattern a bit. A vest, blazer, or jacket can help to break up the pattern or color and add a little more sophistication to your look.^{[24]
X
Research source}
- Try a long vest for an evening out.
- Put on a blazer to make your jumpsuit workplace appropriate.
- You can even try a leather or denim jacket for a fun weekend look.
- A cross-body bag can also help to break up the pattern if you don’t want to wear any other clothes over your jumpsuit.
3
Wear a pair of heels. Putting on a pair of high heels can make almost any outfit look dressy. Try wearing a pair of high heels with your jumpsuit to transform it into a more formal, dressy look.^{[25]
X
Research source}
- To get the opposite effect and dress down your jumpsuit, go for some simple ballet flats or a pair of strappy sandals.
4
Put on a necklace or a pair of earrings. If you want to draw the eye up and away from certain features, then adding a necklace or a pair of bold earrings can also help.^{[26]
X
Research source}
- For example, if your jumpsuit has a deep V-neck that you want to de-emphasize, then try putting on a necklace that falls a few inches above your cleavage. Or, put on some bold, dangly earrings.

Expert Answer

Yes, you can find jumpsuit patterns online or at a sewing store. Just adjust your pattern to fit your measurements.
Question

How do I put it on without an opening?

Community Answer

The neck opening should be wide enough for you to climb in feet first. Make sure you can get in feet first before you hem the neckline -- this is probably not necessary, but you may need to open the top of the shoulder straps and make them longer (or add tying straps).
Question

How can I make the bottom of the pant legs snug at my ankles? Do I use elastic?

Community Answer

Yep! Measure around your ankle with the elastic not pulled tight, but firm. Snip with an extra 1 cm for sewing together last. When you are up to the ankle seams, leave a gap inside of ankle to feed elastic through the seam with safety pin. Check by putting your leg through to see that it's OK, pin where you want it to be in length and then sew ends together, then sew so its flat against the length. Sew down your gap.
