Madonna enshrined in a new advertising campaign showcasing Donatella Versace’s spring/summer 2015 collection. Lean and faintly menacing, she appears, at least in the lens of the fashion photographers Mert Alas and Marcus Piggott, the image of candid aggression.

“Madonna says it best herself: She is unapologetic,” Ms. Versace said the other day. “She is her own woman, a role model who shows other women how we can do what we want, and get what we want, and do so for all of our lives, with no compromise.”
