When a Girl's Beautiful (1947)

Model Adele Jordon breaks up with the model-agency's wealthiest perfume client, and he requests a new model who possesses all of the elements of beauty for their new campaign. Johnny Hanley, a promotion man, submits a composite photograph of the best features from all the models...and comes up with Marjorie Main. Well, maybe not, but anybody who can't guess the ending wasn't paying any attention to the plot premise set-up.
