Daisy Irving:1910, "Actress Daisy Irving poses in what is probably a two-tiered 'lampshade' dress by Paul Poiret, 1910. His loose silhouettes reduced the need for as many underclothes as a 'frou-frou' dress would have done, and the bosom was freed from the confines of a corset," from the book "Decades of Fashion" by Harriet Worsley.
