How to Sew on Suspender Buttons (with Pictures)

Measure 1 inch (2.5 cm) from the center of the back of the pants.

The back strap of your suspenders will need to connect with buttons near the center of the back of the pants. Find the center seam and measure 1 inch (2.5 cm) from the center on one side. Mark the point with a piece of chalk. Measure and mark the other side as well. You can place the buttons on the inside or on the outside of your pants. Placing the buttons on the inside is usually better for a formal look, such as a pair of dress pants. Placing the buttons on the outside is more informal, such as for a pair of blue jeans. Keep in mind that some suspenders have 2 connecting straps with buttonholes in the back and 2 straps with a buttonhole (1 per strap) in front. However, some suspenders are more elaborate than this and the back connects with 4 buttons while each of the front straps connects with 2 buttons.

Mark the placement of the front buttons.

Place the buttons that attach to the suspenders in the front of your pants so they are centered on each side of the front of your pants. The buttons will go in the areas that are just above the front of your hipbone. It is best to use simple buttons to hold suspenders in place, so avoid anything too ornate. Look for buttons that will match your pants and fit through the suspender buttonholes. To get a good fit, you may want to put on your pants and after you have connected the back buttons. With the back of the suspenders connected by the back buttons, sling the suspenders over your shoulders and find where you want to connect them in front. Mark these areas with chalk to indicate where to sew the buttons onto. You'll have 2 buttons on the left side, right side, and back of your pants.

Thread a needle with about 24 inches (61 cm) of thread.

Use a heavyweight thread that matches your pants, especially if you will be sewing the buttons onto the outside of the waistband. Insert the end of a 24 inches (61 cm) strand of thread through the eye of the needle. Then, pull the end of the thread until it is even with the other end. Tie a knot to secure the ends of the thread. You will need to rethread the needle with a new 24 inches (61 cm) strand of thread each time you start sewing on a new button.

Insert the needle through the fabric.

Push the needle in through the fabric where you marked the pants with chalk. Then pull the thread through the fabric until it is taut. If you want to keep the buttons hidden inside of the pants, then sew through the top layer of fabric on the waistband. Do not insert the needle all the way through to the other side. Just try to catch the fibers on the top layer of the fabric. If you want to place the buttons on the outside of the pants, then you can sew all the way through.

Slide the needle through 1 of the buttonholes.

After you have inserted the needle through the fabric, insert the needle through 1 of the buttonholes. Pull the thread all the way through the buttonhole and slide the button down the thread so that it is right up against the fabric.

Bring the needle back down and through another buttonhole.

Next, insert the needle down through the buttonhole opposite the one you just threaded. Pull the thread all the way through the buttonhole until it is taut and the button is right up against the fabric.

Catch the fibers of the pants with the needle.

You do not need to insert the needle all the way through the fabric. You can just catch the fibers with the tip of the needle and then pull the thread through until it is taut. This is especially important if you want the thread to be hidden on the inside of the pants. If you are sewing the button onto the outside of the pants, then you may catch the fibers or sew all the way through the fabric.

Repeat the sequence for a secure stitch.

After stitching through 2 of the buttonholes 1 time, repeat the stitch to ensure that the button will hold and the stitch will not come loose. Depending on the type of buttons, you may only have 2 button holes to sew through. Repeat the process for those holes 1 time. If your buttons have 4 holes, then you will need to sew through each of these holes twice.

Wrap the thread around the base of the button 2 times.

When you have finished stitching the button into place, take the tail of the thread still attached to the needle and loop it around the base of the button 2 times.

Hold the thread and insert the needle through twice to make a knot.

After the second loop hold onto the middle of the thread, and bring the needle around the base of the button to create a loop. Insert the needle into the loop and bring it out the other side. Repeat this 2 times to create a knot around the base of the button. Then, pull on the thread to tighten the knot.

Insert the needle through the pant fabric under the button.

Next, insert the needle through a few fibers on the surface of the fabric under the button. Then, pull the thread until it is taut. This will help to secure the knot you just made. This is optional. If you think the knot is secure enough, then don't worry about sewing under the button.

Snip the excess thread.

Cut the excess thread extending from the stitch you just made. This will ensure that no threads are hanging from the button. After you finish the first button, you can work on the next one. Keep repeating the process until all of your buttons have been attached.
