For practical reasons, you need to wear deodorant with fragrance because otherwise you are gonna inevitably start smelling like shit when you start sweating.

I have been wearing a light cologne at my job because I noticed that almost everyone does. Yes it's almost a social ritual, same way you have to wear a button-up shirt and trousers otherwise clients and associates will think you are unprofessional.
