The actress, who plays Belle in the big screen offering, pulled out all the stops for the event, where she was joined by co-stars Dan Stevens and Luke Evans. Wearing her tresses swept back
from her face, the 26-year-old oozed glamour in a futuristic royal blue dress. However, all eyes were on Emma's endless legs thanks to the gown's daring thigh-high slit at the

'BRINGING BEAUTY TO LIFE' Emma stuck to the legs or chest rule in the chic get-up, which also featured a full, ruched skirt and a red stripe. The Harry Potter favourite chose a
heeled pair of boots and natural-looking make-up for her commitments in the French capital. Dan, 34, who portrays the Beast, stepped out in a khaki suit, while Gaston star Luke, 37, kept
things casual in a black jumper and navy trousers. GETTY Emma Watson wowed in the bold blue dress EMMA WATSON ON BEAUTY AND THE BEAST: IT'S UNBELIEVABLE Their outing comes just days

heroine". _BEAUTY AND THE BEAST OPENS IN CINEMAS ON MARCH 17._
