You have a pair of straight-leg jeans that fit perfectly in the waist and thighs, but the wide leg opening feels dated. It just doesn't look right with your favorite sneakers.

Yes, a tailor can easily make the ends of your jeans slimmer. This common alteration is called "tapering," and it involves narrowing the leg from the knee down to the ankle for a modern, custom fit¹.

For the past 20 years, I've seen countless denim trends² come and go from my factory floor.

The silhouette of the leg is one of the biggest things that dates a pair of jeans.

A simple taper can completely transform a pair of outdated jeans into your new favorite pair.

For a designer like Dean, the leg opening measurement is a critical detail in any design's tech pack because it defines the entire style.

A good tailor understands this and can reshape your jeans with the same precision, giving you a fit that looks intentional and custom-made.

Can a tailor make jeans skinnier?

Your jeans are not just wide at the ankle; they feel baggy all over. You want a closer fit from the thigh all the way down.

Yes, a tailor can make the entire leg of your jeans skinnier. They will taper the seam from the thigh down, removing all the excess fabric to create a slim, modern silhouette.

Making jeans skinnier is a more involved process than just tapering the ankle, but it's a very standard job for a professional.

The process starts with a fitting, where they pin the jeans on you to your desired tightness. A key detail to watch for is how they taper.

For a small adjustment, a tailor will usually take fabric from just the inseam (the inside seam). This preserves the original look of the outseam.

However, if you want a dramatic change from baggy to skinny, a great tailor will take fabric from both the inseam and the outseam.

This is crucial because removing too much from only one side will cause the leg seam to twist as you walk.

Balancing the alteration between both seams keeps the leg straight and ensures a truly professional result that looks like it was made that way from the start.

How much does it cost to make jeans' waists smaller?

You have jeans that fit your legs perfectly, but the waist is too loose. You get that annoying gap at the back whenever you sit down.

It typically costs between $20 and $40 to make a jean waist smaller. The final price can vary depending on your tailor's location and the specific construction of your jeans' waistband.

The cost reflects the detailed work required for a professional result. A proper waist alteration is not a simple pinch and sew. The tailor has to perform several steps.

First, they carefully remove the belt loops from the back of the waistband.

Then, they open up the waistband itself and cut the center back seam. They take in the fabric in the seat and waist, trimming the excess denim.

Finally, they reassemble the waistband, reattach the belt loops in their original positions, and ensure the stitching matches perfectly. It’s like small-scale surgery for your jeans.

While some might offer a quick, cheap fix by adding "darts," the correct method of taking in the center seam produces a completely invisible and much more comfortable result.

What parts of jeans can be tailored?

You have a few pairs of jeans with different fit issues. You're wondering what's actually possible to fix before you decide to get rid of them.

A good tailor can alter almost every part of a pair of jeans. They can adjust the waist, seat, hips, thighs, leg length, and the leg opening to create a fully custom fit.

Think of your jeans as a template that a tailor can sculpt to your body.

From my experience manufacturing jeans, every single one of these dimensions is adjustable. A tailor can essentially replicate the custom fitting process we would do for a brand.

They address each problem area with a specific technique to achieve the perfect balance. For example, a saggy seat requires a different approach than baggy thighs.

They can completely reshape a pair of jeans that are "good enough" into a pair that feels like it was made just for you.

This is why investing in alterations is often a better choice than buying a new pair of jeans that will just have a different set of fit problems.

Jean Part	Common Problem	Tailor's Solution
Waist	Gaps at the back	Take in the center back seam and waistband.
Seat	Sags or is too loose	Take in the center "yoke" seam for a lifted fit.
Thighs	Too baggy or tight	Take in or let out the inseam and outseam.
Length	Too long	Hem the jeans, often preserving the original factory hem.
Leg Opening	Too wide and dated	Taper the leg from the knee down for a slimmer ankle.

Can tailors make pants' waists smaller?

The fit problem isn't limited to your denim. You also have dress pants and chinos³ with waists that are too big and need adjusting.

Yes, tailors can definitely make the waist smaller on other types of pants. In fact, it's often an easier and quicker job for them compared to working on heavy denim.

While jeans can be altered, they are built for durability, not for easy modifications.

The seams are thick, flat-felled, and chain-stitched, which are tough to undo and redo. Dress pants and chinos, on the other hand, are constructed with the expectation that they will be tailored.

If you turn a pair of dress pants inside out, you will usually see a very simple, single-stitch seam at the center back.

There is often a generous amount of extra fabric—the seam allowance—left inside specifically for alterations.

This makes it much simpler for a tailor to open the seam, reduce the waist, and sew it back up cleanly.

The whole process is faster and requires less heavy-duty equipment, which is why you'll find that altering the waist on a pair of chinos is often a standard and very affordable service at any tailor shop.

Conclusion

A tailor can expertly make the ends of your jeans slimmer through tapering. This simple fix is one of many ways they can alter your jeans, giving you a custom fit and modern style.
