D23 Expo: Mandy Moore, Kristen Bell, Reese Witherspoon and more stars hit Disney's red carpet

Disney's annual D23 Expo is about movies, not fashion -- but you can't have a star-studded event without style!

Disney boasts an A-list celebrity roster, thanks in large part to its ownership of the Marvel superhero franchises: Robert Downey Jr., Benedict Cumberbatch and Chris Hemsworth all looked handsome as ever promoting their upcoming "Avengers: Infinity War."

But of course, the best style moments came from the ladies! Best-dressed has to go to "Tangled" star Mandy Moore, who was a real-life princess in a calf-length seersucker frock. With ruffled sleeves and lace detail, the dress was a modern take on Cinderella's classic look.

Reese Witherspoon, Mindy Kaling and Oprah Winfrey took the stage together, and -- it must be said -- two of the three disappointed on the red carpet. Oprah's wedges and vest looked more wacky than whimsical, and Reese underwhelmed in a simple cap-sleeved number. But give it up for Mindy Kaling, whose lovely B&W look was appropriately mysterious for the trio's upcoming "A Wrinkle In Time"!

The three-day convention took place in Anaheim, CA, giving guests exclusive looks into Disney's highly-anticipated upcoming releases. Among the biggest announcements were the newly-confirmed "Aladdin" cast, details about sequels like "Frozen 2" and "The Incredibles 2," and awesome updates from the Lucasfilm and Pixar teams.

Even more details are expected to become public later this month at Comic-Con, where fans will have their fingers crossed for the official "Avengers: Infinity War" trailer.
