Some people also regard nuns' habits or even aprons as uniforms. The uniforms may be genuine, realistic, or they may be sexualized through the use of a very short miniskirt , a very long hobble skirt or a corset , through the use of stockings , fishnet tights , or high heels , or by being made of leather or latex , according to preference. Sometimes uniforms are used according to what activity is being done. For example, someone may wear a nurse's uniform to administer an enema or a police uniform to handcuff and cage someone. Two people may dress as inmates for cell mate -on-cell mate activities in a prison setting or as a submissive to a third prison guard roleplayer.
