We have Watson, a men's fragrance...
We have 221b, a women's fragrance (think Skye!)... http://
And we have Elementary Chapter 4, Holmes' own scent, which men AND women can wear! (If you're THE Woman, that is!)
Descriptions of the fragrances can be found at the links.
This is the same boutique that the writers of Love Potion #9 asked to create a scent based on that unforgettable song! They say, "Here at Love Potion Magickal Perfumerie, we combine over 25 years of experience in crafting artisinal perfumes with care for the historical and magical meanings of the ingredients as well as cutting edge science pertaining to pheromone research and new data on human responses to olfactory stimuli."
Now, as a scientist, I can't speak to any magic effects! But I do know that 1) they are Holmes fans and have been for years; this is the fourth version of Elementary they've concocted (all based on the same ingredients but with slight tweaks in each batch), and 2) they make some wonderful fragrances!
These are limited edition fragrances, and when they're gone, they're gone. (They may be back in some form in the future, but like I said, they'll be a liiiiitle bit different.) If you want to add fragrance to your Holmes fandom, now is your chance!
