Here’s the scenario: You bump in to an old friend — one who’s always trying to single-white-female you in the personal style department.

Friend: Oh, my God! So great to see you. Hey, what’s that perfume you’re wearing?

You: Oh, this? It’s [insert shmancy designer of the moment]. Good to see you, too. Oh, wow — look at the time. Gotta run!

Then, next time you see her, she smells familiar.

Put yourself in the hands of custom fragrance designer Neil Morris and never again shall you suffer the loss of a favorite perfume find to the masses. Morris, you see, creates your personal scent by probing the inner workings of your mind. First, he interviews you, analyzing everything from your favorite cuisine to your dreams. Then he divines a dozen or so notes that tap into every smell you’ve ever loved.

So now, when that friend asks what you’re wearing, just say: “Oh, you know. A blend of linden, Russian leather, peony, and some other things my fabulous new perfumer threw together.”

That’s way more polite than “Smell ya later, psycho.”

Neil Morris, 221 Massachusetts Avenue, suite 501, Boston (617-267-2315 or neilmorrisfragrances.com). By appointment only.
