Fashion Police: The Winners Are Rosie Huntington-Whiteley and Rose Byrne

While RHW nails it in her smoldering white gown, the Damages star crashes and burns in a hot mess

It was all about the flower power in last week's fashion polls!

Everything was def coming up roses for Rosie Huntington-Whiteley, who was smoldering in a white-hot Burberry gown at photographer Mario Testino's London party to take best dressed of the week. The model slash actress just keeps on bringing the glam!

Meanwhile, Rose Byrne's funky Christine Alcalay patchwork dress—at a Gotham magazine bash in NYC—was a look that just wilted. Knowing the Damages star, though, she'll rock something amazing on her next red carpet. Right, Rose?
