THE LITTLE PRINCE (1937)

Staying at a fancy resort, Wladyslawa Majewska is mistaken as a male guest when she is dressed in a skiing outfit. The manager offers her, thinking she is a he, a job as a dancer to entertain the unescorted ladies who frequent the hotel. Wladyslawa goes along with the offer, and keeps the old ladies dancing but falls in love with the best-looking male guest in the process, who thinks she is a man.
