Caron French Cancan (1936) and En Avion (1932) both remind me of a cross between Guerlain Mitsouko (1919) and L'Heure Bleue (1912), and of course first there was Coty L'Origan (1905)--and now we see the loosely knit family tree. French Cancan is to me the more obviously mossy of the two Caron scents. Caron calls it a Floral-Powdery, but for me it registers as Chypre with a prominent violet note which I also find in En Avion, with a dusty, rose-patchouli potpourri-like character. It's a violet lipstick kiss in the air: a retro glamour scent for old-fashioned frills and thrills, Moulin Rouge with class.
It's a point of interest that French Cancan was launched specifically for the US market.
