"The inspiration for the season was equestrian meets bondage," according to designer Nicky Hilton. "So a lot of tailored equestrian looks, but I wanted to sex it up a bit and not have it look so nice. Add a little naughtiness. There's a lot of patent leather, buckles, latex leggings. It's definitely a chic, sexy vibe."
