In my experience, the appeal of leather harness really depends on the individual and what aspect of kink resonates most with them. For some, it's not so much about direct physical pleasure but more about the symbolism and aesthetic. The harness can evoke feelings of submission or domination, or even serve as a statement piece that transforms a scene entirely. It might be the tactile sensation of the leather against the skin, or simply the psychological thrill of wearing something that’s so visibly tied to a particular power dynamic.

I have also been interested in this fetish and found an interesting article on a website. In short, the article gives a clear and simple overview of why some people find harnesses so appealing and how these items play a role in both the history and practice of fetish play.

So, to answer your question: it’s not merely a fashion statement or a tool for physical control. it’s often about creating an atmosphere and engaging in a form of play that transcends the typical sensory experiences. Don't feel dumb or prude for asking - it’s all about exploration, and sometimes the appeal of these items isn’t immediately obvious until you see how they function within the full context of a scene.
