Marybelle Cobb, a plain and old-fashioned girl, is secretary to commercial illustrator Philip Homer, with whom she is secretly in love. When Homer advertises for a girl with perfect leg measurements to be a model for a hosiery manufacturer's advertising, Marybelle, with the aid of her friend Alice, decides to transform herself completely and apply for the job. She wins the much-sought-after appointment against considerable opposition. When Homer's indifference turns to love, Marybelle confesses the deception and all ends well.
