Millie

Millie is fashionable again in London and Wales, where it's Number 32, and in Scotland where's it's reached Number 18, and a possibility here for parents who like the offbeat, frilly, and old-fashioned. Millicent would be the more appealing long form, but many people are using Millie all by its cute self.

Millie was in the Top 1000 here until 1966, peaking at Number 128 way back in 1881; it made a return appearance in 2009, and is beginning to climb. The name got a lot of attention via the 1967 film Thoroughly Modern Millie.

Fashionable relative: Milla or Mila. Tillie is another old-school nickname that, like Millie, sounds modern again.
