Lady Muck is a new 2011 color, which came out for the Spring/Summer season I believe. The BL site describes her as "Powdery periwinkle blue, slightly on the grey side and infused with pearl pigment for a soft, sexy sheen." This baby has definite micro-glitter going on too, giving it that subtle but very present sparkle. I think the pearl infuses with the base and instead of bringing a pearl finish it gives the blue more depth. There is a dusty hint but the pearl drags it up from being too somber. This is two coats with topcoat.
