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?
