Searching for a Signature Scent

How do you find a scent to wear when you don't know how to describe the smells you love and simultaneously you happen to be 36 years old? I know what I don't like (I think?), but finding a classic scent has proven to be a lifelong and super difficult mission for me.

If I liked Chanel No. 5 I'd stop there. But.

This weekend I smelled Boucheron for the first time; I thought it was going to be the one after I did some investigating. Whoa! So wrong (think industrial bathroom disinfectant; odor to cover up toilet smells). I was crushed. The sales associate that helped me with that catastrophe was quick to take me to "younger" scents - a couple Ralph Lauren/Dior/Yves Saint Laurent perfumes. However...she was keen on selling me something "new" which I don't want. I want something that's been around a while and ain't going nowhere.

How do you find a scent? How how how? I'm getting there one sniff and whiff at a time. Stay tuned.
