Koret of California is a name synonymous with innovation and timeless style in American fashion history. Founded in 1939 by Joe and Stephanie Koret, the brand began as a modest endeavor and quickly grew into a powerhouse in the women’s apparel industry. What set Koret apart from the beginning was its knack for combining practicality with sophistication. Stephanie’s talent for designing versatile garments and Joe’s business acumen birthed the Trikskirt—a revolutionary adjustable skirt that became an instant success. This innovation propelled Koret to unprecedented heights, amassing over a million dollars in revenue within just two years. This marked the beginning of Koret’s legacy as a pioneer in women’s sportswear and separates.

The Koret brand became known not just for its fashionable designs but also for its trailblazing use of fabrics and garment technology. They introduced wardrobe staples like the Slim Hip Slax and Pleetskirt, which redefined women’s sportswear with their superior fit and ease of wear. However, their crowning achievement came in 1961 with the invention of Koratron, a permanent-press fabric that revolutionized the industry. Koratron earned Koret millions in licensing revenues, cementing its position as both a fashion and technological innovator. Throughout the mid-20th century, Koret’s ability to blend practicality, elegance, and groundbreaking design turned the brand into a household name, solidifying its influence in department stores and beyond.

Though the brand underwent significant changes after being acquired by Levi Strauss in 1979 and later by Kellwood Corporation, Koret’s enduring legacy is a testament to its ingenuity and impact on American fashion. From its roots in San Francisco to its eventual distribution in mid-priced stores across the United States, Koret of California remains an icon of vintage fashion. For collectors and enthusiasts, each Koret piece represents a piece of history—a blend of innovation, style, and functionality that continues to captivate decades later.
