Émilie Marie Bouchaud (14 May 1874 – 14 October 1939), better known by her stage name Polaire, was a French singer and actress. She was known for her extremely tight corset, dubbed the wasp waist, reportedly measuring less than 16 inches (410 mm), and her eccentric stage presence, which generated mixed receptions.
Polaire's finances suffered from a series of actions by the French tax authorities and she struggled to find stage or screen roles as she aged. She may have suffered from depression.
She died in 14 October 1939, aged 65, in Champigny-sur-Marne, Val-de-Marne, France. Her body was buried at the Cimetière du Centre, in the eastern Paris suburb of Champigny-sur-Marne.
