There was a lot going on at the Philipp Plein Spring 2017 show: a set that resembled a carnival, leather-clad children running around, shirtless men ogling the female models. Despite all of that, it was the evening’s surprise guests – Fergie, who opened the show with a performance; Fat Joe, who closed with “All the Way Up”; and Paris Hilton, who walked the runway – that stole the show.
