Now that she's engaged to Australian actor Liam Hemsworth, Miley Cyrus is like Australia's in-law and last night's was like the first family Christmas party where she showed off her engagement ring.

Miley has been favoring plunging necklines—and now exposed bras—presumably because she loves the shit out of that full-torso necklace she keeps wearing.

I thought for sure this hippie was like a surfer or something, judging by the trinkets in her hair and the devil-may-care manner in which she threw this outfit together, but it turns out that Clare Bowen is in fact an actress.

I actually think that Kym Wilson's necklace is really cool, but not with this dress. It needs a higher neckline so it can appear to be an awesome metal collar, which I think was maybe the intention of the designer. The way she has it here is the equivalent of someone wearing a tie with a Polo shirt.

Gowns: Tahnya Tozzi, Peta Murgatroyd, and Anna McGahan.

White three ways: Abbie Cornish, Yvonne Strahovski, and Claire Holt.

Veering away from solids are Phoebe Tonkin, Natalie Imbruglia, and Jessica McNamee.

Michelle Van Der Water and Stephanie Jacobsen are very Annie Sez-strip mall. Meanwhile, Erika Christensen looks almost unrecognizable. (At first glance, I assumed she was an older Australian actress whom I was unfamiliar with.) The takeaway here is one of the only valuable pieces of advice Tyra ever dished out on America's Next Top Model: Shiny fabric is not your friend.
