Hold up: Is this an Olsen I'm looking at or Hilary Duff? I did a double take when I saw the singer at TRL's goodbye party [1]. I can totally see Ashley rocking this unique look.

Like many of the other guests, Hilary opted for an LBD [2]. But hers isn't any old black dress; it has a sexy sheer layer. She then cinched her ensemble with a wide leather belt and kept her feet simple with black patent pumps. She dressed up her earlobes with large earrings — her signature. Are you feeling this chic new Hilary?
