Denim-Dictionary

Denim is a durable cotton or cotton-blend twill textile, typically used to make jeans, jackets, and (for adorable children and highly confident adults) overalls.

To create denim fabric, the horizontal weft threads pass under two or more vertical warp threads. This process makes diagonal ribbing of denim that distinguishes it from cotton duck, which may sound like a stuffed animal but is actually the name of a similar twill fabric.

The quintessential American fabric originated far from America. The earliest use of denim refers to a serge material (a twill fabric commonly used in military uniforms) from Nimes, France in the 1850s. Historically, fabrics were named after their place of origin —serge de Nimes later evolved to “de Nim.” The fabric then was not the cotton denim we know today. It was a blend of silk and wool. Today’s all-cotton denim was first created in England and later perfected in American mills.

Denim work pants have been around since as early as the 17th century, when nobodycould tell how they looked after 5pm because electricity had not been invented. But the first official blue jean dates back to May 20, 1873, when the U.S. Patent and Trademark Office granted patent #139,121 to Levi Strauss & Co. and Jacob Davis for the process of placing rivets on men’s denim work pants for strength.

Blue jeans are pants made of denim, typically featuring riveted reinforcements. In 1873, Levi Strauss and Jacob Daviscombined quality denim and patented copper rivet reinforcements, creating the first-ever pair of Levi’s® jeans.

Real denim, also known as raw denim or dry denim, refers to denim that hasn’t gone through any pre-washing or shrinking processes inproduction. Most jeans in stores today have gone through some sort of pre-washing process to soften the fabric and reduce shrinkage post-wear and wash.

Shrink-to-Fit™ refers to raw, unsanforized denim, meaning that no shrinking wasapplied during the production process. The fit, wear and finish of garments made with Shrink-to-Fit™ denim are all unique to you, depending on how you wash, wear and care for the jeans. Before 1960, this was the only way to buy jeans: you deliberately purchased them too big and then shrunk them down to your size.

A classic Levi’s®design, referring to jeans or pants designed with two back pockets, two front pockets and one smaller fifth pocket (sometimes referred to as a “coin pocket”) on the right hip.

An update to the original Levi’s® Trucker Jacket, the Sherpa Trucker Jacket is cold-weather-proof with fuzzy sherpa insulation and soft quilted lining in the sleeves.

The Levi's® Trucker Jacket is the first of its kind and the prototype for all jean jackets today. It's a denim jacket complete with riveted reinforcements, shank button closures and historic Levi’s® design that originated in 1962.

The typical western shirt features a stylized yoke (the shaped pattern piece that forms the upper part of the shirt) on the front and back as well as distinct pockets, like a “Barstow” (a Levi's® term for a single-yoke pocket) or “Sawtooth” (another Levi’s® term for a double-yoke pocket) design. Western shirts typically have snap closures instead of buttons to minimize the need for repair.

Contrary to its name, anti-fit is not a pair of jeans that doesn’t have or want a fit. It’s just a slightly looser cut of our men’s jeans that deliberately leaves some room in the butt area. A silhouette that pays tribute to bikers—the ultimate thrill-seekers of the 1950s —think: a little extra comfort and an effortless cool factor.

The iconic stitching on the back pockets of Levi’s® jeans is referred to as an “Arcuate” because of —can you guess? —its arc formation. The Arcuate trademark is one of our most globally recognizable design details, and almost certainly the first thing you notice about, uh, a person’s backside if they’re wearing Levi’s®. Fun fact: we even used it on our earliest “waist overalls,” the original name for the blue jeans patented in 1873.

Our jeans are so tough that even two horses pulling in opposite directions couldn't tear them apart —or so this patch suggests. Even today, when horses are generally not used to measure tensile strength, the leather rectangle over our back right pocket illustrates our legendary durability and reinforces our status as the originator of patented riveted clothing.

A series of tight zigzag stitches used to reinforce stress points and provide strength and durability. During World War II, we used bar tacks instead of rivets in an effort toconserve metal.

When sewing two pieces of fabric together —such as the leg of a pair of jeans —about an inch of extra fabric is retained on the outside of the seam to protect it. If left as-is inside the leg, this double-flapped strip will eventually fray and destroy the seam. Flat busted seams are sewn and then pressed flat, creating a reinforced closure that covers raw edges.

The edge of a piece of fabric where it’s been turned in and sewn. It most commonly refers to the bottom of a pair of jeans or a pant leg. Lately, raw hems (unfinished hems with frayed edges) have been back in style. Thank you, this saves us a step.

A rivet is a piece of metal hardware that helps to reinforce a garment. The first riveted work pants were patented on May 20, 1873 by Levi Strauss & Co. and Jacob Davis and are known today as blue jeans. Rivets on our 501® Jeans are made of copper and are designed to add strength to the pockets.

Buttocks. Behind. Bum. You know exactly what area we're referring to here. But since this is a dictionary, here's our technical definition: the seat extends from the top of the jean to just below the pockets, where the legs begin, on the back of a pair of pants or jeans.

Quality meets durability. Selvedge denim is woven on traditional narrow-width shuttle looms and produces a signature self-finished clean edge –and “self-edge” is where the name “selvedge” comes from. You can identify a pair of selvedge jeans by looking at the inside of the outseam. When you roll the pant leg, you’ll find this crisp strip with a stripe down the middle, and this artful and functional detail (it won’t unravel!) is what sets selvedge denim apart from the rest.
