Originally a small-town manufacturer of adult work clothing, it has become best known for its children's clothing, especially bibbed overalls. The original children's overalls, dating from the early twentieth century, were intended to let parents dress their children like their fathers. According to the company, sales of the product increased after Miles Kimball, an Oshkosh-based mail-order catalog, featured a pair of the overalls in its national catalog in 1960. As a result, OshKosh began to sell their products through department stores and expanded their children's line.
Children's clothing made up 15 percent of the company's sales in 1979; by 1993 that number was 95 percent.
Oshkosh B'Gosh clothes are no longer made in Oshkosh. Downsizing of domestic operations and a massive in outsourcing and manufacturing at Mexican and Honduran subsidiaries saw the domestic manufacturing share drop below 10% by the year 2000.
Today, the company sells accessories, jeans, pants, shirts, sweaters, t-shirts, tank tops, and its trademark overalls. The company produces clothing for babies, infants, toddlers, kids (4-7), and youth (5-14); however, it no longer manufactures clothing in adult sizes due to poor sales. The company also has over three hundred stores in the United States of America.
