It's two gorgeous gals in the same ethereal dress.

Alec Baldwin's calmer half, Hilaria Baldwin, was glowing in a Dolce & Gabbana floral frock last week at Elton John's AIDS Fundraiser in New York City. The new mom kept her look minimal, with a diamond ring, loose hair and natural makeup.

Back in November 2012, Katy Perry wore the same off-the-shoulder gown to the Dream Foundation Celebration of Dreams in Santa Barbara. The "Roar" singer accessorized her look with dangling emerald earrings, side-swept hair and a bejeweled belt that cinched her waist.

While both women look amazing, we have to give this to Katy. The Dolce & Gabbana dress is slightly more glam and fits better at the neckline on the California girl.

But Hilaria, who had a baby just two months ago, still looked luminous. Keep it up, girl!
