I've been trying to remember what this movie was called. Sadly I only remember a few details. It was older, roughly the time that Marilyn Monroe was around. It was about 2 women, I think sisters, who moved to France to take up the family business as performers. It was burlesque-like dancing, with giant feather fans and such. They were uncomfortable with it at first and then gradually became very famous.

Thanks for any help!

Sounds like Gentlemen Marry Brunettes (http://www.tcm.com/tcmdb/title/17558/Gentlemen-Marry-Brunettes/)
