Gemma Arterton Wows In Louis Vuitton Negligee Dress For Unicef Halloween Ball

The negligee trend is one of this season's sexiest and last night, Gemma Arterton showed us why.

The Brit beauty wore a gunmetal Louis Vuitton slip dress for the UNICEF Halloween Ball in London. Think less scary more smouldering, think spaghetti straps, floral and lace detailing, shimmery silver eye makeup and a sleek updo. Shazzam!

Gemma sauntered along the red carpet at One Mayfair looking totally fabulous. Who said you had to go all out ghoulish or grannyish a la Heidi Klum to celebrate Halloween in style?
