Who was a style hit at the Emmy Awards?

The 66th annual Primetime Emmy Awards took place last night (August 25), with Breaking Bad and Modern Family stars emerging victorious at the Nokia Theatre in downtown Los Angeles.

Orange is the New Black stars Taylor Schilling and Laura Prepon were among the stars who made an impact on the red carpet, in addition to Girls creator Lena Dunham and her co-star Allison Williams. But who was a style hit and who missed the mark?

We thought Lena Dunham was Lady Gaga for a split second, as she graced the red carpet with platinum blonde hair and a striking, pink and red layered tulle Giambattista Valli skirt. Her Girls co-star Allison Williams opted for an elegant strapless ballgown with black bow and yellow band.
