Isabel
Isabel is hugely fashionable again, a century after its first wave of success. Easy to see why: it's ladylike (a la Isabel Archer in Henry James's Portrait of a Lady) and melodic, traditional yet offbeat. Isabel sounds smart as well as pretty. Only downside: so many other little Isabels, Isabelles, Isabellas, Belles, and Bellas. Isabelle is the French version, Isabella the Italian one, and Isobel the Scottish spelling.
