From the Creeping Irrelevance Tumblr blog:

This indicates it is from The Half-Breed, a 1952 film, and the cast list for that film credits several cancan dancers - Caleen Calder, Marietta Elliott, Shelah Hackett, Betty Leonard, Mary Menzies, and Shirley Whitney:

The costumes are just like the one in this famous photo, so it must also be from The Half-Breed or the costumes were re-purposed:
