Yves Saint Laurent Beaute's star product for spring is a blockbuster! The limited edition Palette Y-Mail (available in two shades: a pearly finish or silky finish) was inspired by Stefano Pilati's Y-Mail baggage collection. The multi-shaded powder is embossed with the historic address of the Yves Saint Laurent House, a nod to the fashion house's prestigious history. It's housed in a chic black suedine pouch bag stamped with the address. Each of the two harmonies is composed of three buildable shades to be used separately or superimposed.  The Face Highlighter (pearly finish) is meant to be applied to the points on the face that catch the light such as the forehead, the cheekbones, the nose, and the chin. It can also be drawn out over the entire face for a radiant complexion. The Blush Harmony (silky finish) is meant to be applied to the curve of the cheekbone to enliven the complexion.  Each retails for $78. The Palette Y-Mail compacts have become popular with collectors of late. The intricate design of the powders and the elegant case make them dearly coveted.  Shop early if you like this item.  It won't last long. by Dave Lackie
