Raf Simons has selected 22-year-old actress Jennifer Lawrence as the next face of Dior's iconic Miss Dior handbag, making her the youngest ambassador the brand has ever signed. Her campaign for the bag will appear in March 2013.

"Like everyone else, I first discovered Jennifer Lawrence in the roles she played in action movies," Simons said. "Her youth and her classic beauty, but also her force of character and the complexity she's capable of embodying at such a young age, are, for me, both unique and very moving."

Lawrence, who sat front row at Simons's debut show for Dior in July, and recently appeared on the cover of British Vogue, acknowledged that "it's impossible to be in the industry without getting even the slightest introduction to fashion." She added, "It's such a dream to represent an iconic brand that is synonymous with high fashion."

She's not the only actress who's taken on the role of Miss Dior. Marion Cotillard has been its face since 2008 and will continue working with the brand. Mila Kunis starred in a print and video campaign for the bag this year.

Like any father figure would, PPR chief Francois Pinault defended Hedi Slimane against some of the less kind things critics have said about his debut collection for Saint Laurent. In the process, he also sent a thinly veiled zinger in the direction of Cathy Horyn, and may well have put an end to the war of words between the critic and the designer.

"Hedi Slimane did a remarkable job. I liked last Monday's fashion show very much — the Saint Laurent collection exceeded my expectations," Pinault said. "The house needed both a renovation and a return to its roots and, with Hedi, we have started down that road. I totally stand by the house of Yves Saint Laurent and the decisions made by its teams or its artistic director, and I didn't appreciate that some people tried to use me by linking my name to chatter about invitations or the seating of this or that person."

By "some people," Pinault may have meant Horyn, who wrote in her review of the collection that Pinault expressed dismay when he found out Horyn hadn't been invited to the show. The unfavorable review spurred Slimane to write an open letter posted to Twitter and other missives decrying Horyn as a "schoolyard bully and also a little bit of a comedian." Those tweets have now been deleted. One wonders, now that Pinault has gotten what effectively is the last word in this saga, whether he asked Slimane to put those barbs away in the first place?

Nicolas Ghesquiere admits that Balenciaga "had a size issue" when he first started designing for the house 15 years ago. Now, he wants to make sure that the cuts of his innovative, highly regarded clothing can be worn by women of all shapes and sizes.

"We started very skinny, it's true," Ghesquiere said in an interview with The Sunday Times. "Strangely, we didn't have fit models at all to begin with — just to give you an idea of the size of the company. So we did fittings on the girls at the studio and they were often quite petite. I had a tendency to think good cut and small size, but a good cut should come in big sizes, too. That's what I want to focus on — it's the cut, not the sizing, and if people see that they can wear something in a big size, then I did my job."
