In just a few years, the global star has become a veritable fashion icon, with his gender-fluid outfits inspiring millions of people around the world, as a new study reveals.

The British singer is a popular style icon in no less than 27 countries around the world, where his outfits have been searched for more than any other celebrity in 2021, according to a study conducted by Money.co.uk.*

Billie Eilish was relegated to second place among the most popular celebrity style icons this year.
Her outfits are top of the searches in 23 countries around the world. After making the cover of Vogue UK and being snapped in a breathtaking Oscar de la Renta dress at the MET gala, the singer has been inspiring fashion fans in Belgium, Brazil, Malaysia, Portugal, Switzerland, Turkey, Morocco, Senegal and India.

Is gender-fluid fashion the real style icon of 2021?

Between them, Billie Eilish and Harry Styles clearly appear to have dominated the fashion limelight this year. And their taste for gender-fluid looks no doubt has something to do with that. Both stars have clearly distinguished themselves with their willingness to break codes and stereotypes, reflecting broader changes underway in society.

Whether it's a suit or evening dress for Billie Eilish, or flared pants, open shirt and shiny gold chain or a dress with a feather boa for Harry Styles, both use fashion as a new form of self-expression.

Kim Kardashian: Still got it

In the rest of the ranking, Ariana Grande takes third place, with her outfits being the most-searched in 14 countries around the world, including France. Then comes Kim Kardashian -- whose style rules the way in Armenia, Botswana, Namibia and Australia -- and her two sisters, Kendall and Kylie Jenner, who are also still popular this year.

This year's new entries include Rihanna, Cardi B, Justin Bieber, Addison Rae, Kate Middleton, Doja Cat, Selena Gomez, David Beckham, and two Blackpink singers -- Rosé and Jisoo -- whose outfits will be closely followed throughout 2022.
