SAKS AND SANCHEZ: Hugo Boss pulled out all the stops Wednesday to entertain more than 60 top Saks Fifth Avenue executives at a dinner in a penthouse space in the Trump SoHo hotel, including general managers of Saks stores from around the country, in town for a company conference. The night’s guest of honor was New York Jets quarterback Mark Sanchez, who regularly wears Hugo Boss but is not officially affiliated with the brand — yet. “I’m one of those guys who is — I think the expression is ‘a long-suffering Jets fan,’ ” said Ron Frasch, president and chief merchandising officer at Saks, who was clearly excited to hang with the gridiron hero. However, he joked that Jennifer De Winter, Saks’ executive vice-president of stores, had whispered, “Who’s Mark Sanchez?” In between a musical performance from Ashford and Simpson and a promotional video for Hugo Boss featuring Bravo’s Andy Cohen, Hugo Boss Americas chief executive officer Mark Brashear exhorted his Saks guests to boost Boss sales to more than $1 million per store this year. He noted the brand’s sales were up 23 percent last year at Saks. Sanchez declined to answer any questions on the record (on the advice of his manager).
