Recognizing the possibility of volume business in overalls, The H.D. Lee Mercantile Company opened its first garment factory in Salina, Kansas, to produce overalls and work jackets.

The success Lee experienced making quality work wear eventually changed the focus of the company from a wholesale grocery and dry goods distributor to an apparel manufacturing giant.

Lee created the first one-piece coverall: the iconic Union-Alls are designed to protect clothing both below and above the waist.

Because cars were not as dependable as they are today, drivers doubled as auto mechanics. Crawling under automobile dirtied fine clothing both inside and out. When a mechanic delivering autos to a Salina dealership heard about Lee's new overall factory, he asked the factory superintentdent to sew a jacket to a pair of pants—akin to the popular one-piece “Union Suit” undergarment but for outerwear. The rest is history. The following year (1914), Lee registered the term, “Union-Alls” with the U.S. patent office and added them to its product line. Within two years, as Lee ads suggested, there was "a suit of Union-Alls under the seat of every auto."

As a result of the Union-Alls popularity, The H.D. Lee Mercantile Company grew its manufacturing capabilities to keep up with demand.

The H.D. Lee mercantile Company looked beyond the small community of Salina, Kansas for a larger labor force. New factories opened in Kansas City, Missouri; South Bend Indiana; Trenton New Jersey and Minneaplois, Minnesota. From 1915-1919 all Lee factories focused on producing just Lee Union-Alls to meet demand.

On March 17, 1917, The H.D. Lee Mercantile Company moved its headquarters from Salina, Kansas to Kansas City, Missouri.

Taking advantage of the metro's larger work force and better freight rates, the new 9-story headquarters opened at 20th & Wyandotte.

The Buddy Lee doll was introduced to promote Lee overalls. Over the next 40 years, he helped to introduce new products offered by Lee.

Becoming a promotional success at county fairs and in store windows, Buddy Lee dolls were first made of composition and later of molded plastic. When it became cost-prohibitive to manufacturer the doll, Buddy Lee was discontinued in 1960. Buddy Lee returned in 1998 to promote the company’s Can’t Bust ‘Em Dungarees line, aimed at 17- to 22-year-old males. Buddy Lee, "Man of Action" appeared in ads as a heroic figure who survived all kinds of certain doom, prompting his human co-stars to marvel at the durability of his jeans. Lee offically retired Buddy Lee in 2006.

After consulting with working cowboys and champion rodeo riders, Lee introduced its cinch-back ‘Cowboy Waist Overalls' of 9 oz. denim for men (101) and boy’s (101B).

Lee established brand loyalty early with current and aspiring cowboys and rodeo champions, in part by improving fabric, fit and finishes to meet their specific needs. Copper rivets were replaced with "scratch-proof" stitching to reinforce back pockets, protecting saddles—the cowboy's most valued possession. Lee Cowboy Pants later became known as Lee Riders.

Working with Canton Mills of Canton, Georgia, Lee developed the strongest and bluest denim in the market for durable work and western wear.

Used exclusively by Lee, this new 11.5 oz. denim was made by twisting the yarn tighter than previously made and engineered to be harder to snag, tear or rip yet pliable and comfortable. In 1931, Lee changed the name to “Jelt Denim."

Lee was the first garment manufacturer to use a 'hookless fastener' in cowboy pants, overalls, coveralls and playsuits.

Lee held a national contest to name its new zip-front overalls, coveralls and playsuits. The winning name was 'Whizit,' based on the sound it makes. Advertisements using Babe Ruth and other well-known celebrities helped the Whizit gain immediate popularity. The proof was in the numbers. In a photo taken after the 1927 National Corn Huskers Contest, eight of the ten winners were wearing Lee Whizits.

Lee made the workwear worn by America's work force.

"The Great Lee Success Story" advertisements celebrated workers wearing Lee products in manufacturing plants from coast-to-coast, ranging from steel and automotive to railroad and aviation. This led to Lee's slogan: The Jeans that Built America. In 1937, Lee became the nation's largest manufacturer of workwear with sales at $6.4 million

Lee's Jelt denim survived Ripley's Believe It or Not! 26-mile crawl across untreated concrete.

To prove Lee's continued dedication to quality and durability, Ripley put Lee's Jelt Denim Overalls to the test. The buttons held their shape after being ironed with a 5-ton steamroller. The denim survived a 26- miles crawl across untreated concrete. One man stood in the pockets of overalls worn by another and the stitching stayed secure!

During World War II, Lee supported the war effort, manufacturing shirts, pants and flight suits for the United States military.

Continuing to advertise through prosperity and depression, a full-page advertisements in LIFE Magazine for Lee workwear included the following notices: "War conditions make it impossible to meet the growing demand for Lee Work Clothes. Your Lee Dealer is receiving his fair share of all we are able to make after the needs of our men in the armed forces have been supplied. If your Dealer is out of the Lee you want please ask him to reserve one for you out of his next shipment."

1946 ushered in the birth of the "twitch" label.

With the new 101 Lee Riders, Lee introduced their now famous “Lazy S” decorative stitching-still in use today on the back pockets and the “Twitch” leather label.

Lady Lee Riders were introduced to the market.

In 1947, the untapped women's jeans market welcomed Lady Lee Riders, “Authentic Cowboy Pants, button-fly, Sanforized, 8 oz. coarse weave denim.”Made with the same button-front fly, 5-pocket construction as men's Riders, Lady Lee Riders came with the same guarantee to fit or your money back. The primary difference? Lady Lee Riders were made with a small dart in the yoke to create a more fitted waist for the female physique and with a fuller seat and hips than men’s Riders.

Lee outfited the 52-foot tall Big Tex at the 1952 Texas State Fair

In 1952, Lee took on 364 hours of work to sew a shirt and pants for Big Tex, the 52-foot tall symbol of the State Fair of Texas. The jeans alone, the largest authentic Lee Riders ever manufactured, required 100 yards of denim and 5,900 yards of thread

Denim's shift from workwear to pop culture fashion began.

Worn by movie stars like Marlon Brando in 1953’s “The Wild One” and James Dean in 1955’s “East of Eden” and “Rebel Without a Cause,” jeans became a symbol of American youth, boosting sales dramatically.

Lee offered a new slim and trim, authentic western cut with a "dressed up" feel.

Lee Westerners were the first dress-up jeans and jackets ideal for sports, hobbies, campus, on the job, or in the saddle. Made of Lee's trademarked Westweave fabric, this lines created a new concept in slim, trim, authentic western cuts pants and jackets. Rodeo champion Casey Tibbs served as Lee's spokesmodel. In 1960, Lee offered Lady Lee Westerners for "gals on the go."

Fashion needs of high school and college students were met with national advertisements offering the new Leesure's trim, "skin tight" silhouettes.

Supporting the new tag line "The Clothes You Need for the Life You Lead," Lee added the promise of fashion to its longstanding quality guarantee—all at an exceptional price.

Bell bottom jeans and painter jackets became popular on the college scene.

Dry cleanable or machine washable, this garment was designed to give long and satisfactory service. The prices ranged from $4.95 to $7.95.

A Lee embroidered denim design became a fashion favorite.

Introduced as "Freeway Jeans" in a campaign featuring supermodel Shelly Hack, who later starred in Charlies Angels, the pants were often referred to as Lee's Rainbow Jean.

Lee's new tagline "The Brand That Fits" was launched.

In the early 1980s, Lee released several new fits and fabrics for women, including the London Riders, which catered to women with fuller fits and a high-end stretch denim fabric. This positions the company to become the top-selling female jean manufacturer in the country.

A Lee jean jacket made the cover of the Rolling Stone magazine adorning rock star Bruce Springsteen. It doesn't get much better than that.

Riders became a separate brand of “easy-going, honest clothes” designed specifically for the mass market, available at Wal-Mart and K-Mart.

Lee created its National Denim Day to create awareness for breast cancer research.

Lee National Denim Day was the result of an internal team effort to find a cause that was of concern to both Lee consumers and employees. After extensive research, the answer became clear: breast cancer. Lee hired a celebrity spokesperson to promote Lee National Denim Day and promote breast cancer awareness. Companies that chose to participate asked employees to donate $5 in exchange for wearing jeans to work. From 1996 to 2015, the campaign raised more than $98 million. Beneficiaries included Susan G. Komen Breast Cancer Foundation, Women’s Cancer Programs of the Entertainment Industry Foundation andthe American Cancer Society.
