Why did changes in women's cycling clothes cause controversy in the 1800s?

In the 1800s, changes in women's cycling attire—specifically the adoption of "rationals" or knickerbockers—caused controversy because they challenged prevailing standards of modesty and femininity.12

During the 19th century, women’s fashion was dominated by restrictive garments like corsets, multiple petticoats, and long skirts, which were considered essential to maintaining a "respectable" and feminine appearance. When women began cycling in the 1890s, these cumbersome outfits proved impractical and dangerous. To accommodate the physical requirements of the bicycle, women adopted "rationals," which were inspired by the earlier, controversial "Bloomer costume" advocated by Amelia Bloomer in the 1850s.1234

Because these outfits featured trousers or divided skirts, they were widely viewed by society as immodest and unfeminine. Despite the backlash, the practical necessity of these garments for sports like cycling and gymnastics eventually helped shift attitudes toward more functional clothing for women.421
