What better way to promote a film called "The Bling Ring" than to wear sparkly jewelry?
The 23-year-old Brit wowed on the red carpet with a sequined black and white Chanel gown (which showed off the pint-sized star's back) and three small but dazzling earrings on her left ear. Now that's bling!
We're relieved that Emma wore such an impressive (and wardrobe malfunction-free) gown. It was loads better than the feathered Christopher Kane she wore the day before which showed some unflattering Anne Hathaway-style dart nipples.
Watson has certainly been going for a more sexy and mature look these days; the actress wore a cute mini when she arrived in Cannes on Tuesday and took us by surprise in a slashed Prabal Gurung gown at the 2013 Met Gala that showed off lots of skin.
What do you think of Emma's bling?
