Rumors swirl season upon season that Stefano Pilati is done at Yves Saint Laurent. Pilati replaced Tom Ford in the mid-aughts, and while some of his collections have been lauded, others have been slammed. What’s more, Pilati is known for being a pain-in-the-rear. He’s a party boy, and he doesn’t like playing nice.

Now the New York Post, via Fashion Wire Daily, reports that Spring 2011 might really, truly, be the end of the road for Pilati. But the collection was undeniably strong. And the shoes will certainly be a best-seller. So we think he still has more time.

However, if Pilati is leaving, who will succeed him? Riccardo Tisci has popped up in the past, but we think that’s an unlikely scenario. Now Olivier Theyskens is the name on every tongue. Sure, Theysken’s collaboration with Theory means he’s learning to create more commercial clothes, but his aesthetic is just so frilly, so goth. Not YSL at all.

You know who would be good? Proenza Schouler. They missed out on the Valentino gig a few years ago, but that’s okay. They’re ready now. And they create the kind of clothes that the YSL customer wants: Wearable, sophisticated, and forward at once. Let’s start a Proenza to YSL campaign! (If, in fact, the rumors prove true.)
