On the red carpet: Beyoncé, Sienna Miller, Katy Perry, Ashley Madekwe

Beyoncé wore a sheer Gattinoni Couture dress studded with jais stones to the Tidal X:1015 benefit concert in New York. 

The design’s inspiration — a photo of a woman who’s skin is ‘scarified,’ or artfully scarred — is new to me. The image appears on Beyonce.com.
