Mia Wasikowska is Very Valentino

Alice is definitely grown up!

Mia Wasikowska shows off her gorgeous Valentino Couture dress at the premiere of Alice in Wonderland at London’s Odeon Leicester Square on Thursday evening (February 25).

The 20-year-old actress recently sat down with ET about working with such notable actors as Johnny Depp, Anne Hathaway and Helena Bonham-Carter.

Mia shared, “Everybody sort of puts a lot of themselves into their characters … everybody on the film and set is a little bit crazy, and I love that. But just to see how brave he [Johnny] is in those choices, and bold, it’s very exposing, so it was really cool that someone can take that on in the way that he did.”

Alice in Wonderland opens in theaters NEXT Friday, March 5. Check out a brand-new clip from the film below! 10+ pics inside…
