Then, as the waltz became popular in the 1820s, full-skirted gowns with petticoats were revived in Europe and the United States. In the Victorian era, petticoats were used to give bulk and shape to the skirts worn over the petticoat. By the mid 19th century, petticoats were worn over hoops. As the bustle became popular, petticoats developed flounces towards the back. In the 1870s, petticoats were worn in layers. Colored petticoats came into fashion by the 1890s. In the early 20th century, petticoats were circular, had flounces and buttons, in which women could attach additional flounces to the garment.

She had travelled to Connemara for inspiration, where she saw a woman wearing a traditional red flannel petticoat.
