Anyone tried adding leather harnesses to their outfits?

I've been seeing a lot of interesting fashion trends lately, especially those incorporating unique accessories to elevate an outfit. Specifically, I'm thinking about leather harnesses. They seem like a bold statement piece, and I'm curious how people integrate them into their wardrobe without making it look too costume-y or over-the-top. Does anyone have experience with these sorts of accessories? I'm open to experimenting with my style and adding something a little edgy, but I’m not entirely sure where to start. Any tips on styling them subtly or making them versatile would be really helpful!
