This week, enough butterflies descended upon Paris Haute Couture to please Mariah Carey; Jean Paul Gaultier told Vogue that "Life was a butterfly!" and when it came to the beauty looks, designers Alexis Mabille and Yiqing Yin were also in agreement. A few of them were shown on pretty fascinators (hey, British royal family) and plastered over models' entire faces. In non-insect-inspired looks, Cara Delevingne also showed up as the Bride du Chanel with a blunt under-eye of silver glitter, and Julien Fournie found a way to make baby's breath actually look beautiful. Whether or not you're in the market for a $30,000 dress, click through our slideshow of the prettiest beauty wizardry and looks of the week.
