According to good old Wiki, apparently drinking Champagne from the shoe of a courtesan was a custom that originated in the 18th-century. On March 3, 1902, Prince Heinrich of Prussia visited a Club while in the United States to pick up a ship built for his brother. The sisters planned a bacchanalia for the visiting prince. During one of the dances, a prostitute’s slipper came off and spilled Champagne – naughty, naughty. One of the prince’s entourage drank the Champagne, and thus he began the trend of drinking Champagne from a woman’s shoe.
I say it’s high time we started drinking Champagne from shoes again. Only, let’s do it the Christian Louboutin & Piper Heidsieck way.
