Madeleine Vionnet's beautiful new winter collection is the outcome of unceasing research work and contains some of the most interesting and successful clothes which have been shown in Paris this season. Her models, divested of all that might be considered superfluous -as well as her creative ability- are in a class all by themselves, being far removed from what in former days characterized designers of "feminine frivolity." Madeleine Vionnet is recognized the wide world over as the inventor and foremost exponent of chastened and modernized simplicity in dress. A kind of simplicity far more sophisticated and complex than an hitherto known elaboration!
