GOING NOWHERE: Stefano Sassi, chief executive of Valentino Fashion Group, which has a stake in Proenza Schouler, squelched ongoing speculation that he’s about to step down as he stood on the sidelines of the young designer’s pre-collection event in Florence. “I’m staying where I am — the Valentino line is getting a lot of positive feedback. It’s more modern and it’s on an interesting path,” said Sassi. “I’m keen on seeing future results.” As for Proenza Schouler, he said VFG plays a supportive, productive, and industrial role for the designers. “They are full of ideas and there’s a lot of potential,” said Sassi, who added it was unlikely a Proenza Schouler store would open this year.
