Vogues of 1938

The blueblooded Van Kletterings are broke; debutante Wendy, slated to remedy this by marrying rich bore Henry Morgan, instead leaves him at the altar and goes to work as a model for high-fashion clothing designer George Curson, whom she soon falls for. But he's happily married (at least on his side) and going into debt financing a show to please wife Mary's desire for stardom. Vindictive Morgan, jealous of George, hopes to hasten his ruin. Can the House of Curson be saved? (imdb)
