According to Clarence House, the ravishing bride was wearing a scent called White Gardenia Petals by Illuminum, a little-known U.K. brand.
The website for the perfume describes the scent as "delicate and nuanced...fragrant as a vase of white flowers quivering in the breeze by an open window." Aside from gardenia, the perfume includes whiffs of coconut leaves, ylang ylang, jasmine and a "seaside location." (Hmmm, where have we heard that before?)
Moments after the news broke in the country, the 50-milliliter bottles vanished from store shelves and now there's a two-week waiting list. The fragrance, which retails for $115 is going for double that on eBay.
The brand was launched in 2007 by former celebrity hairdresser Michael Boadi, who has worked with Kate Moss and Naomi Campbell.
Michael Donovan, a spokesman for Illuminum, told the Daily Mail that there's been a "phenomenal response" to the perfume, not just in England, but across the world.
"Orders have come in from dozens of different countries, but most of our customers have come from the U.S," said Donovan. "It's charming to think that so many people abroad are interested in the wedding."
(Oh, and it wasn't just the bride who smelled delicious on the big day—Westminster Abbey and a different kind of throne did, too. Middleton requested her faves from perfume company Jo Malone be delivered to scent the Abbey throughout, and had orange blossom and grapefruit candles placed in the royal bathroom.)
We suspect the women buying White Gardenia Petals will find it worth the wait, because as everybody knows, you smell like a princess, you land a prince.
