According to Clarence House, Kate wore White Gardenia Petals by Illuminum, a little-known British brand.
A description on the company website describes the scent as
'fragrant as a vase of white flowers quivering in the breeze by an open window, this is a delicate and nuanced scent.
'The top note of coconut evokes a seaside location, while heart notes of muguet, ylang ylang and jasmine breeze bring a trio of white flowers into play.
'Amber wood underscores this capricious and light bouquet.'
The fragrance is available in two sizes: a 50ml bottle and a 100ml bottle. There is currently a wait list for the 50ml bottle but the 100ml bottle can be purchased immediately.
