While attending a birthday party at the Shores bar in Santa Monica, the usually scantily clad pop star wore a see-through dress -- like, completely sheer. The black mesh number revealed both her bra and panties, but it doesn't look like Katy was unaware of this before she left the house. Well, at least it was floor length, right?
The recent divorcée wore biker boots, a leather jacket and a rosary with the revealing look. We probably wouldn't have even taken a second look at Katy's outfit had it not been so blatantly risqué. It definitely reminded us of Carine Roitfeld's sheer and lingerie pairing, even though Katy's take was not quite as glamorous as that of the esteemed fashion editor.
Do you think Katy pulled off the look? Or did the outfit's wardrobe malfunction factor outweigh its glamour potential? Check out the photos and tell us what you think.
