When we first saw this shot of Leona Lewis, we were immediately obsessed. We couldn’t figure out if it was the hot pink lips (genius), or the horn-rimmed specs (librarian chic) or the side-braid (so on-trend it’s almost over) — but we soon figured it out. It’s her slightly metallic dove gray nails! How fabulous are they? Pale, shimmery gray strikes the perfect balance between a go-with-everything neutral and an unexpected, statement shade.
