Check out this interesting article on perfume bottles. It's written by Chandler Burr of "Emper of Scent" fame:
"They are ingenious works of art (Donna Karan's delicate apple of glass and metal). They are pieces of humanity (the curve of JLo's behind in your hand). They are semaphores (Issey Miyake's inverted cone), runes (Castelbajac) and fertility idols (Jean Paul Gaultier's Le Male). They are Second Empire (Guerlain), Disneyland (Lolita Lempicka), 1950's Paris (Miss Dior), alien organism (Comme des Garcons 2), mystical riddle (Kenzo Air) and spaceship engine (Sander for Men).
They are perfume bottles, of course."
