NEW YORK - US designer Donna Karan sent models down the runway in an explosion of color while Victoria Beckham plumped for safari chic in stark contrasts on the fourth day of New York Fashion Week on Sunday. Karan’s spring/summer 2015 collection for her DKNY line was one of infinite color and texture encapsulating modern classics, sports elements and playful geometry in “a sexy mix of street and chic.” An iconic New York designer, she paid homage to the Big Apple as “the world in one place” and as multicolored, multicultural and multitasking.
