Actress Chloe Moretz was a vision in a violet Christian Dior dress with beautiful lace and floral paneling at the Dior Illustrated: Rene Gruau and the Line of Beauty event in London.

If you recall, Tinsley Mortimer paired the same pretty piece (from the designer's Spring 2010 collection) with a bright pink clutch and shoes for the 7th Annual New Yorkers for Children Spring Dinner Dance back in April.

While Chloe did a good job of warming up her look with black tights for fall, the bright color and playful nature of Tinsley's accessories read hot, hot, hot!

See who else wore this dress!
