Gemma Arterton proved basic is beautiful when she strutted down the red carpet at the Omega ‘Lost in Space’ anniversary party at Tate Modern in London on Wednesday (26.04.17) in her glamorous simple black frock. The brunette beauty couldn’t contain her excitement as she flashed her pearly whites to photographers before she made her way into the venue. Drawing attention to her slim pins, the actress teamed her simple above-the-knee gown with a pair of around-the-ankle stilettos.
