Gemma Arterton's Expensive YSL

Gemma Arterton attended the private viewing of "Amazon" an exhibition in aid of Sky Rainforest Rescue looking beautiful in a Grecian-style white jumpsuit by Yves Saint Laurent.

Gemma's YSL chain-embellished crep jumpsuit costs a staggeringly high $5,100 at net-a-porter.com.  Steal The Style alternative - head down to a haberdashery for some chains and customise your own jumpsuit - would cost a heck of a lot less!
