The usually “too mature for her age” Holmes took a juvenile approach to the red carpet, wearing a Louis Vuitton floral frock, which seemed like something her daughter Suri would wear! She paired the high-necked pastel-hued dress with black nylons, Casadei heels and a Chanel bag, resulting in a shockingly youthful look.
