Fashion mishap?

The Zima sisters at the 2007 Hollywood Style Awards. I don't know what movies Vanessa and Yvonne are in, but you might remember eldest sister Madeline, right, as Gracie Sheffield from The Nanny. Anyway, what kind of dress is Yvonne (middle) wearing? Take a look at the top of the dress. Doesn't it look like a bra to you? It does so to me. The whole ensemble looks like a tube dress lowered down to below the breasts and topped with a bra. Not a good look. And with that hairdo, she seems to scream 1992. But anyhoo, it's a good vintage outcome, especially if she sported that look unwittingly.
