Rihanna wore a custom Jacquemus dress resembling a bathrobe at the launch of Fenty Hair in London on Sept. 16. Later in the night, she changed into a 2006 John Galliano gown.

Rihanna graced New York Fashion Week with her presence, then hopped across the pond to spend a little time in London during the city’s own fashion week.

Rihanna isn’t the only person to rubber-stamp the formal bathrobe lately. At the Cannes Film Festival, juror Isabelle Huppert hit the Horozion: An American Saga red carpet in a Balenciaga bathrobe dress. While Rih is all for the off-the-shoulder look lately, Demna designed the French actor’s dress with an elevated collar.
