Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

Although Sylvia seems to be having somewhat of a revival among trendsetting baby namers, we'd still opt for the even gentler and more unusual Sylvie. Despite being dated in its native France (where it was popular during the 1950s and 60s), in English-speaking regions it still feels fresh and international without being unfamiliar and has a cosmopolitan, international air. It debuted on the US Top 1000 in 2016.

Elsie is a sweet vintage nickname-name turned modern star. After a 30-year hiatus, Elsie started climbing the US popularity list 20 years ago and is still headed for the top.

Millie is back. It's a popular name throughout much of the English-speaking world, and broke the US Top 100 in 2024. Millicent would be an appealing long form, but many people are using Millie all by its cute self.

Maisie, a charming name long popular as a nickname for Margaret or Mary, entered the Top 1000 as itself ten years ago and continues to rise. Game of Thrones star Maisie Williams helped propel the name back into the limelight, along with the that of her character, Arya.

Poppy, unlike most floral names which are sweet and feminine, has a lot of spunk. Long popular throughout the rest of the English-speaking world, Poppy is finally starting to rise toward the top in the US, where it entered the Top 1000 for the first time in 2016.

With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry.

With its sharp, succinct sounds and cool, laidback style, Eli is a popular choice among parents today. Compact and punchy, it is a Biblical name with plenty of charm.

Rosy-cheeked and cheery, Rosie (also spelled Rosy) has been standing on her own for many decades, back to the days of 1943 musical Sweet Rosie O'Grady. She's one of the perky nickname-names that are filling the popularity lists of other English-speaking countries. In the US, she came back to the Top 1000 in 2013, after a 30 year hiatus. In 2023, Rosie was one of the fastest rising girl names.

Josie is jaunty and friendly: among the most winning of all nickname names. She's been on the Social Security list since records began being kept.

Charlie is a friendly, boyish nickname name now used slightly more frequently for girls than boys, with over 2200 baby girls named Charlie last year versus about 2100 boys. That makes Charlie one of the most evenly-balanced and most popular unisex names around today.

Pippa, a peppy condensation of Philippa that turns it from serious to sprightly, has come into the public eye in a big way via the former Kate Middleton's sister.

Birdie was until recently a middle-aged Ladies' Club member wearing a bird-decorated hat --but now it's just the kind of vintage nickname (think Hattie, Josie, Mamie, Millie) that's coming back into style in a big way. Actress Busy Philipps named her baby Birdie (inspired by First Lady Lady Bird Johnson), as did soap star Maura West.

Edie is part of the Evie-Ellie et al family of cute and friendly short forms that sometimes stand on its own. Briefly popular in the 1960s, it could well be due for rediscovery. It's already a fashionable choice in the UK, where it has ranked just outside the Top 100 for several years.

Joining the likes of Coco and Fifi, Gigi has a style but some may feel it lacks substance. Model and TV personality Gigi Hadid (born Jelena) has likely drawn attention to this name, while designer Cynthia Rowley may have inspired parents to use it as a given name by choosing it for her daughter.

Scout, a character nickname from To Kill a Mockingbird (her real name was Jean Louise), became a real-life possibility when Bruce Willis and Demi Moore used it for their now-grown middle daughter, followed by Tom Berenger a few years later.

Lula has a firecracker personality, a singing and dancing extrovert. Interesting that Lulu was a Top 100 name when the Social Security list was born in 1880, but it's been sliding ever since and has not been in the Top 1000 for decades. Modern parents in love with Lulu might well reverse that trend.

Although Disney's cute deer was a male, Bambi has always been used for girls. It first appeared on the charts in 1943, the year after the Disney movie was released. Bambi featured in the Top 1000 from 1954-1964 — a decade where girl names ending in I, like Lori and Teri, were big — and again from 1977-1982.

Coco came to prominence as the nickname of the legendary French designer Chanel (born Gabrielle) and has lately become a starbaby favorite, initially chosen by Courteney Cox for her daughter Coco Riley in 2004. At first it was the kind of name that the press loves to ridicule, but we predict Coco's heading for more broad acceptance and even popularity.

A unique combination of a surname feel and dainty femininity, Lacey is a favorite in the UK where it ranks in the Top 500. Likely derived from the name of a place in Normandy, it might occasionally be considered a diminutive to Wallace ("Welshman") or Larissa ("citadel").
