How To Take In Slacks

Today, I’m eager to impart my own insights and knowledge regarding the technique of altering slacks to fit better. This can come in handy if you’ve shed some weight, stumbled upon an amazing pair of slacks that happen to be slightly oversized, or if you’re looking to rejuvenate a pair of old slacks. Mastering the skill of taking in slacks can be incredibly beneficial.

Gathering the Tools

Before we get started, let’s make sure we have all the necessary tools. You’ll need a sewing machine, thread in a color that matches your slacks, a pair of sharp scissors, pins, a measuring tape, and an iron.

Measuring and Pinning

The first step is to try on the slacks and determine how much they need to be taken in. Start by pinning along the side seams, taking care to maintain an even and symmetrical fit. You can also pin at the back center seam if needed. Once you’re satisfied with the fit, carefully take off the slacks, making sure to leave the pins in place.

Removing Excess Fabric

Next, use your scissors to carefully cut along the pinned lines, removing the excess fabric. It’s important to leave a small seam allowance to ensure that the slacks can be easily sewn back together. I recommend leaving about half an inch of extra fabric.

Sewing the Seams

Now it’s time to sew the seams. Set up your sewing machine with the matching thread and adjust the stitch length to a medium setting. Start at the top of the slacks and sew along the pinned lines, backstitching at the beginning and end of each seam to secure the stitches. Take your time and sew slowly, ensuring that the seam is straight and even.

Trying on and Adjusting

Once you’ve sewn both side seams, try on the slacks again to make sure the fit is just right. If any adjustments need to be made, now is the time to make them. If the slacks are still too loose, you can repeat the process and sew another seam closer to the original one.

Pressing and Finishing

After you’re satisfied with the fit, it’s time to press the seams. Use your iron to carefully press the seams open and flat. This will give the slacks a professional finished look. If there are any loose threads, trim them with your scissors.


Taking in slacks is a valuable skill that can save you money and give new life to your wardrobe. With a few basic tools and some patience, you can achieve a perfect fit every time. So go ahead, grab those slacks that have been sitting in the back of your closet, and give them the makeover they deserve!
