Cara Delevingne didn't mind anybody's dress code when she showed up to Princess Eugenie's wedding [1] in a tuxedo. But not just any tuxedo — Cara's had a satin waist belt affixed to match with the trim on her cropped trousers, and her buzzy printed tie polished things off, fastened pristinely around the collar of her white blouse.

Read on to see Cara arriving with editor Derek Blasberg and completely owning this darn show.
