The other is Jo Malone Orange Blossom, a scent the Duchess enjoys so much she had candles of it burning as she walked down the aisle at Westminster Abbey.

The Duchess of Cambridge reportedly loves the scent of Dior Dune and has been using it for some time. It's a warm summery fragrance with lily, bergamot, vanilla and sandalwood. Perhaps she's dreaming of warmer climes when she spritzes on the scent on a chilly English morning.

For her 2011 wedding to Prince William, the Duchess of Cambridge chose a springtime scent that was redolent with buttery white floral notes by little-known British Perfumer Illuminum.
