It’s a battle of East versus West in this Real Housewives edition of Who Wore It Best!

On Wednesday, October 23, Beverly Hills castmate Lisa Vanderpump stepped out for the Season 4 premiere party held at Hollywood’s Boulevard3. While word on the street is that Lisa avoided her co-stars for most of the night, she certainly grabbed the attention of the rest of the guests!

The 53-year-old Housewife showed off her age-defying figure in a body-hugging number by Alexander McQueen ($7,160). The cut-out gown gave fans a good look at her (ahem) ample assets, while adding all the glitz and glamour that’s become a trademark of the star!

But the Lady of the BH isn’t the only Housewife to don this eye-catching dress. When the Real Housewives of Miami returns for the Season 3 reunion, Alexia Echevarria will wear the exact same number — minus the addition of an adorable dog.

Despite all the drama that’s sure to surround the episode, Alexia will invariably come out on top. (At least fashionably, that is.) The Cuban-born star will pair the gorgeous gown with a matching crystal-embellished belt ($995), while adding emerald jewelry for a fun pop of color.

Whose take on the glamorous Alexander McQueen gown do you like best?
