Did Malaika Arora Khan copy Naya Rivera's gown?

Malaika Arora Khan recently turned up the heat in a black floor-sweeping gown by a top American designer at an event. Although full-sleeved, the dress revealed as much as it covered. Incidentally, American TV show actress Naya Rivera had displayed serious cleavage in the same gown last year at an awards ceremony. Both ladies kept their makeup minimal and their hair classic.
Malaika finished her top knot bun with a delicate headband, and Naya went for shoulder-length curls. While Naya wore bracelets and dramatic gold cuffs, Malaika kept it simple with a statement gold ring. Who gets your vote?
