This isn't just any Chanel store window. This one is in Hawaii. If you look very closely (or click on the photo to enlarge it), you can see the reflection of palm trees in the glass.
Just for fun, here is a short list of the most popular girls' names from Hawaii (with Leilani, meaning "heavenly lei," being the most popular):
1900–1939: Kuʻulei ("my lei"), Leināʻala ("the fragrances are wafted"), Leialoha ("lei of love"), Leinani ("beautiful lei"), Leimomi ("pearl necklace")
1940–1969: Puanani ("beautiful flower"), Leialoha, Haunani ("beautiful snow"), ʻIwalani ("royal Frigatebird"), Uʻilani ("heavenly young beauty"), Ululani ("heavenly inspiration")
1970–1989: Malia (Mary), Kēhaulani ("heavenly dew"), Kuʻuipo ("my sweetheart"), Maile ("the maile vine"), Noelani ("heavenly mist"), Puanani
2000–2005: Malia, Noelani, Māhealani ("full moon night"), Kuʻuipo, Alana ("awakening" - although this is also an English name), Keikilani ("heavenly child")
Coolness and rain symbolize happiness in a warm climate. Mist is a symbol of romance. Lei means a child, because a beloved child is carried like a lei on the parent's shoulders. A child can also be a flower or a bud, regardless of its sex. Modern parents tend to be more prosaic, calling a child a child, as in Keikilani and Kamalani, in which keiki and kama both mean "child".
