In earlier centuries, buttons found on the back of a dress as opposed to the front were originally intended to give the appearance of wealth in a woman, as wearing such a garment implied the woman could afford servants to help her dress. Many such dresses, especially the most frivolous and those intended for formal occasions, were difficult to impossible for the wearer to fasten by themselves. Back closures on female clothing remained common in Western fashion even through the Industrial Revolution, when servants became rare except to royalty and the wealthiest of women. Even then, back closures were still favored by women who wanted to appear wealthy or more attractive. It is for this reason that back closures have more often been associated with clothes intended for smarter occasions, such as formal events, religious services, or professional wear.
