These stuff can lift up your mood, be used as a cue for cleanliness and even improve work performance. Obviously, to smell good too.
Let's keep it simple, what fragrances (perfumes/colognes) do you use? Maybe a signature scent of yours?
I don't really change fragrances a lot since it's always hot here in my place and I like to smell fresh and citrusy.
I mostly use Chanel Allure Home Sport, Acqua di Gio and Perry Ellis 360 Red.
