Lady Gaga wore a Moschino peplum dress whilst backstage at the iHeartRadio Music Festival, which was held at the MGM Grand Garden Arena in Las Vegas last week.

I love the way she respectfully channelled Audrey Hepburn with this look, and continues to keep us entertained on her fashion roller-coaster.

Anna Faris wore the same dress last night when she arrived at the Ed Sullivan Theater for a guest appearance on the ‘Late Show With David Letterman’.

The ‘What’s Your Number?’ star only accessorized with Christian Louboutin ankle strap ‘Boulima’ pumps.

Gaga’s Fendi glasses, Ferragamo clutch, leather opera gloves, diamond jewels and pose takes this look on another level beyond Anna, so Gaga wins very easily for me.

You can buy their Moschino dress from Saks.com.
