Who Wore It Best: Emmy Rossum vs. Pippa Middleton

It’s a peach-off!

Emmy Rossum wore Tabitha Webb’s Breast Cancer Summer Blossom dress ($391.88) in Beverly Hills last week.

Then, we have Pippa Middleton wearing the exact same frock to the Waitrose Summer Party at London’s Natural History Museum tonight.

Oooooh, whichonetopick???

The exclusive from my-wardrobe.com was designed to raise funds for the CFDA’s Fashion Targets Breast Cancer, with 30% of every sale donated to the cause.

Middleton, who is a columnist for Waitrose Kitchen magazine, sipped champers with ITV morning presenter Phillip Schofield inside the museum, of which her big sister is a patron.

“Met Pippa Middleton tonight, as you do,” This Morning’s co-host tweeted.  “Delighted to report, she’s lovely :)”

Middleton paired her peach dress with nude heels, the same ones she sported last night with a little back (and vury sexy) Webb dress.
