The kings of opulence and embellishment, Domenico Dolce and Stefano Gabbana, lent undone chignons some Spanish flair via vibrant red roses and ruffled carnations for their Spring ’15 runway show. Since then we’ve seen celebs embrace the concept using understated ivory blooms instead. Poppy Delevingne celebrated Chanel No. 5 last night by tucking a few buds around her bun; Queen Bey donned a cream rose crown for a recent Instagram snap; and Tony Award-winning actress and singer Lena Hall sported fresh white flora at Lincoln Center’s Annual Fall Gala. We’ve dubbed it the Dolce effect, as it appears everything is coming up roses.
