Being and clean is imperative. Body odor, foot odor, and cigarette odor are all turnoffs. That goes both ways.
Beyond that, something faint is nice. Overpowering perfume might make me sneeze. Some fragrances are pleasant, some are irritating to my nose. Just a dab of the right one is great.
Some shampoos have great smells, and clean hair is very good. That smell should complement any perfume.
I too very much like vanilla.

Essential oils and scented candles add a nice touch. Many are pleasant and relaxing. I'm not sure which I find stimulating, but I think vanilla may be one. I experienced something that seemed like butterscotch a couple of months ago and really liked it.
A slight taste of wine on a woman's lips can be tantalizing.
Last but certainly not least, the smell of a woman's genitals can be intoxicating. Stale is bad. Fresh with natural secretions is good. Actually, it's really, really good.
You are a master at this, but as we know YMMV, so thanks for asking
