Solange Knowles attended a party in London last night held by Net-a-Porter to celebrate the addition of Dolce & Gabbana clothing to their site. She wore a black blazer over a sharp white button-down shirt, starry print leggings from the fall 2011 Dolce & Gabbana collection, and black patent heels.

How do you feel about the mix of tailored pieces with leggings in this look?
