How to shorten Levi’s Engineered Jeans explained

Published on July 8, 2022

We recently added an option for special request alterations that fall outside of our regular services. For example, shortening the inseam on these vintage Levi’s Engineered Jeans is far more time-consuming than chain stitch hemming. After all, you would not want to lose the sloped hem shape that uniquely identifies these by cutting them straight like regular jeans. This calls for more than our trouser or chain stitch hemming services.

For this style, we first record the size and shape of the original hem by creating a pattern to recut the newly positioned leg opening. After, we remove the inside panel at the hem stitch by stitch to keep it intact.

These jeans have a twisted leg, so measuring the inseam can be tricky. On jeans with a leg twist, you can’t just follow the inseam line down with the measuring tape. Instead, you must follow the shape of the leg down without turning under the seam. Following the inseam line on a twisted leg will ultimately mean that leg will be slightly shorter.

Finally, after the jeans are cut-down, the original inside hem panels are sewn back into the leg opening. Finished, the jeans keep the look of the original factory sewing and stitching while being customized to a concise length.

What is chain stitch hemming?

Published on January 8, 2020

Chain stitching is a type of stitch produced by a sewing or embroidery machine. The name chain stitch comes from its looped chain-link-like appearance. In sewing, a chain stitch has a single stitch line on the top side and a looped chain-like stitch on the bottom side.

Single, double, and triple-needle chain stitching is popular in denim clothing and similarly constructed garments. It is usually found on high-stress seams which often incur stretchings such as the center seat seams, yokes, panel seams, inseams, and waistbands. The triple-needle is more often used in workwear.

Tension in the stitch pulls the fabric into a slight pucker, allowing a bit of stretching. A favorite in garment manufacturing because it provides a strong durable stitch that can easily be undone if needed. The tension creates a decorative puckering effect which is especially visible on denim seams and hems, as the fabric shows signs of aging, washing, and wear.

What is hemming?

Hemming is the sewing process of shortening the length or finishing the bottom edge on a pair of jeans or pants. Hemming uses a method of double folding into itself the raw fabric edge of the leg openings to make a clean smooth edge.

What is chain stitch hemming?

Chain stitch hemming is when a pair of jeans or pants are hemmed with a chain stitch sewing machine. The hem of most jeans is traditionally sewn with chain stitching about 1/2″ above the bottom edge. Some makers choose to make the height of the hem taller or shorter as a choice of design aesthetic. The below photo is an example of a chain-stitched hem with a traditional-sized hem.

Why are some jeans made with a regular stitch at the hem?

We see jeans without chain stitching predominantly in the work of novice denim brands or designers inexperienced in the category of denim. However, being a neophyte is not the rule as seen on the below hem of Levi’s jeans. Even the biggest most celebrated brands sometimes use factories accustomed to producing low-end / discount denim and commonly disregard chain stitching if not a design decision.

To be clear, we don’t know why any brand would purposely choose to use a regular stitch at the hem, especially if they are well-established denim brands, however, some are known to do so. Take A.P.C. for example, which is a major French brand that has a generally well-educated denim customer base and has been pretty successful in making jeans for a long time. They purposely choose to go with a hem fold that is larger than most jeans, plus use a single needle stitch (trouser styled). This is obviously an aesthetic choice.

That said, customers that send us A.P.C. jeans for hemming or tapering, almost always request traditional chain stitching and hem size. Very rarely do our alteration customers request trouser-styled hem construction, which may be an insight into the thinking of U.S. enthusiasts.

What are whiskers on jeans? How are they made naturally and commercially?

Published on March 4, 2016

Denim enthusiasts know the best whiskers are made by starting with a pair of dark raw denim jeans and just wearing the hell out of them. An example can be seen in the image below of a 1-year-old 15-oz pair of Williamsburg jeans. On the other hand, the average consumer may be asking, “what are whiskers on jeans?” Because they only know the jeans they buy in stores come with a worn-in look and can’t tell what looks natural and what looks manufactured.

If you don’t have the patience to break-in a pair of raw jeans or can’t deal with the rules of wearing them – choosing rather buy pre-washed ones. You should at minimum be educated on what looks real or good in terms of washes. This is the first article in a new series where we break down many of the effects seen in naturally aged denim jeans. We will explain how the effects are created to make prefabricated washes look naturally aged.

What are jean whiskers?

Whiskers, also called mustaches, hige, crease lines, etc., can be seen on the jeans below, which formed naturally from the state of raw denim jeans. Lines from repeated stretching and pulling motion develop at the front hip area. Crease lines extend out from the crotch and across the out-seams of the hips. As raw jeans age. Abrasion on the high points of the surface fades and becomes brighter than the surrounding areas as indigo or dye rubs off.

How to put whiskers on jeans

On pre-washed or commercially processed jeans, fabricating whiskers is one of the most copied and difficult effects to achieve. They are artificially created by hand sanding the jeans before they are washed and still in “raw denim” form. On lower-priced jeans, the effect usually looks fake, like drawn white lines. On jeans that garner higher price tags, sometimes known as premium denim, more time and effort is spent to make the whiskers look as real as possible by fading them in and out, mimicking high to low points.
