This week was all about trying something different. And the winners are...

Eva Mendes in Oscar de la Renta at "The Other Guys" premiere in New York. This posh, light gray sensation comes complete with a detachable skirt, which Eva left behind while out and about in New York the same day.

Iman rocking a tangerine-colored Victoria Beckham dress at the Essence 40th Anniversary Party in New York. The bright hue and metallic belt pairing really livens up this otherwise simple sheath. The supermodel adds an edgy touch with black nails and matching black, peep-toe Louboutins.

Lea Michele posing in a strapless Giambattista Valli gown at the Fox Summer TCA All-Star Party in Los Angeles. I would've loved to have seen Lea throw on some gold jewelry to accentuate this dress, which has "Grecian goddess" written all over it.

Karina Smirnoff rocking a red bandage dress at the BlogHer Kiss & Tell Summer Party  in New York. While Karina could manage to look hot in a trash bag, this dress has certainly proved one of her spiciest yet.

Estelle sparkling in a Doo.Ri minidress at Grey Goose Entertainment and BET's "Rising Icons" Series event in New York. The gem-encrusted, bright turqoise paneling along the sides of this dress is to die for! I also love how Estelle opted for bright pink Jimmy Choo sandals when a lot of celebs would've deferred to nude or black. It really makes for a refreshing and unexpected color palette.
