This was so charming. It was both of its time, and timeless. Can a girl who's jealous of her roommates --both engaged -- pick herself up, become more interesting (to herself, but also others), and find a good husband? Darcy's accomplice in this maneuver is Gloria, an actress and wise person who prescribes a regimen of physical training which leads to an attitude adjustment, and increased self-confidence. At the same time, Gloria helps manufacture a fiancee, one who's in England, so no possibility of the roommate ever meeting him in New York.
Everything comes to a head when Darcy's escape to a mountain camp is identical to her roommates' honeymoon plans. An acquaintance-cum-friend pretends to be the missing fiance, but troubles ensue, from Darcy falling for the friend, the erstwhile fiancee getting press for getting knighted, and the friend falling for Darcy. In the end, of course, it all works out, but what a romp to get there!
