Fifth Avenue pioneer transforms "fashion first" from cliche to credo.. The Goods Bergdorf's and Barney's bring on the high-end trends: Saks will forever be the birthplace of classic American clothing retail. Calvin Klein, Donna Karan, Michael Kors, Kate Spade and Ralph Lauren dwell here; so do the Pradas, Badgley Mischka and Ermenegildo Zegna. The Extras Saks gets props for its petite and Salon Z (sizes 14-24) women's collections, as well as their cozy onesies and birthday-party bests for the little ones. The beauty salon features Elizabeth Arden's expert stylists. From baubles to bridal registry, each department is a boutique to itself, boasting staffs who not only sell the good life: they set the example.
