Sally Singer, thanks for being so smart about things of beauty, and what they mean. Speaking of, we Catbirds have been wearing all sorts of sparkly nails lately. I'm stuck on Bring on the Bling, made with virgin diamond powder, the perfect wash of sheer shimmer for the summer. In the winter, I'll call it my Snow Queen look.
