(This is one that I forgot for outfits and Fetish wear Thanks to for reminding me about this one)

A spanking skirt is a type of BDSM clothing meant to facilitate spankings. From the front, it looks like a typical pencil skirt, but part of the back is open to reveal the buttocks. It is usually worn by women; the men's equivalent would be chaps. A spanking skirt may also be known as a spank skirt or spanking dress.

Spanking skirts are typically made of fetish material, such as leather, latex, or PVC. The purpose of the skirt is to make access to the buttocks easier for a spanking, or simply to display the wearer's derriere in private or at a fetish event. Like most fetish wear, spanking skirts are tight and often display other fetish elements like corset-type lacing or buckles. Colors are varied, especially in latex, but favourites remain red and black. A spanking skirt can be incorporated into humiliation play as well as spanking. It is often paired with other fetish wear such as corsets and heels.
