The recent shake-up at Tiffany, involving the replacement of CEO Frederic Cumenal and the departure of its design director, is said to be predicated on disappointing sales and a resultant decline in share prices. Since last fall, many upscale shops in the area have complained about a negative impact they felt was caused by the hullabaloo around Trump Tower—both rubber-necking and security barricades. A change in marketing emphasis toward a younger consumer—witness the hiring of Lady Gaga for advertising—and designs reflecting that shift are reportedly in the offing to reverse disappointing balance-sheet figures. Not everyone is worried, though. Tiffany & Co. has weathered many a storm in its 180 years, and the ambiance on the floor is still serene, the merchandise still beautiful.
