It depends on my mood. One of my all-time favorites is Escada that was discontinued. It's sweet and almost cotton candy-scented. I've recently been into fruity, citrusy, earthy tones though...maybe because of summer.
I like to mix up my perfumes (just because I get bored of smelling the same thing every day) and my boyfriend likes it. Kind of like he'll never know which one I'll wear : P
