SAVE-THE-DATE: In the past, Ralph Lauren has chosen to present resort with private appointments at the company’s showroom or, at times, to not show it to the press at all. This year is different. On June 6, Lauren will stage a resort runway show at his women’s flagship at 888 Madison Avenue. It’s the first time the designer is putting resort on the runway, and by doing so, he is making a making a major statement for the ever-growing importance of the season. Oscar de la Renta and Calvin Klein Collection are among those houses that have staged or continue to show resort on the runway.
