Leopard accessories really do work like a neutral.
The above is easy, comfy.
For a sexy spin I would add some nude strappy sandals and gold jewelry. I wouldn't button up too far on the blouse. I'd keep my legs bare and make my bag a clutch so I'd show I am not all business.
A real leather classic belt is so worth the investment. I don't know why I waited so long to include them in my life.
