If your workplace has an actual fragrance-free policy, the best option is simple: follow it.
Those policies may exist because coworkers, customers or patients have sensitivities.
If fragrance is permitted but you simply want to smell subtle, use less product rather than applying a strong fragrance and trying to disguise it.
A light roll-on application can remain closer to the body than a large fragrance cloud from repeated spraying.
But workplace rules come first.
Loving perfume and being considerate of the people around you can absolutely coexist.
