We’ve covered celebrity looks daily here on Who What Wear over the past 20 years. (Yes, it’s our 20th anniversary this year!) From effortless street style looks we aspire to re-create to showstopping red carpet ensembles that have made us gasp in delight, the A-list provide us with endless fashion inspiration that entertains, surprises, and influences our own daily outfits. And behind every incredible celebrity outfit is a creative, skilled, and hardworking stylist who has made the vision come to life.

In tandem with their clients, celebrity stylists craft unforgettable fashion moments—many of which are often discussed for years to come. From Ariana Grande’s Glinda-inspired looks to Zendaya’s magnificent movie premiere outfits and Hailey Bieber’s breathtaking after-party ensembles, we’d be remiss not to credit the behind-the-scenes geniuses responsible for their memorable looks.
