Another day, another WWIB? poll featuring Gemma Arterton.

The British actress wore this breath-taking Valentino Pre-Fall 2010 strapless ballgown when she arrived on the red carpet for the “Prince Of Persia: The Sands Of Time” World Premiere in London back in May.

She let her embellished gown do the talking as she didn’t add many other jewels, just simple studded diamond earrings and a silver ring.

Son Ye Jin – who was your Best Dressed last week – wore the same gown to the opening ceremony of the 15th Pusan Film Festival in South Korea last week.

The Asian star also kept her look simple, but her rings were more dramatic.

It was a very hard choice, but in the end I picked Gemma mostly because she’s taller, therefore her skirt doesn’t look as crushed as Son Ye Jin’s. Also I love her red lippie.
