Back in May Sienna Miller and Jude Law announced to the world that they were back together by attending the Costume Institute Gala at The Metropolitan Museum of Art in New York City.

She wore a plunging midnight blue Emilio Pucci Fall 2010 gown which had a tiered embroidered skirt and a rise and fall hem.

Lorraine Schwartz Diamonds and strappy Pucci sandals completed her look.

Valeria Solarino showed us that lighting can indeed strike twice when she wore the same dress to the “Vallanzasca – Gli Angeli del Male” Premiere during 2010 Venice Film Festival this week.

With her smoldering darks look the Italian actress wore her dress with Jimmy Choo Feline snakeskin shoe boots.

Valeria wins for me as I love the deeper plunge on her dress. I much prefer her heels, the lack of accessories and her darker locks makes this look feel a lot sexier.
