Fashionista is proud to present Deal or No Deal, in which a group of style insiders check out a discount fashion item and answer that pressing question - is it worth it?

Notte by Marchesa bow dress, originally $780, now $390 at Bergdorf Goodman Online.

Ali Lang, MTV stylist: “It’s expensive, but with Fashion Week around the corner and Restaurant Week in full effect, it is either liposuction or that dress, which will make you look a size smaller..If it works, then I am buying two in case I spill something on one. So yes, definite deal especially if you compare it to the cost of
lipo!”

Gina Kelly, Seventeen Fashion Director: “This is a total deal. I love that Marchesa does a “secondaryâ€? line. Buying a Notte is like buying Marchesa—which makes you one step closer to looking like Sienna Miller!”

Jenny Feldman, ELLE Fashion News Editor: Deal. This dramatic black Marchesa number cleverly incorporates Grecian-style draping, metallic detail, and a strapless neckline—all very of-the-moment. While I’d prefer to drop the big bucks on a less formal, day-to-evening dress that could go from work to cocktails, at $390, I couldn’t turn down this one either.

Fashionista: Deal, but only if you’ve got at least one party where you know you’ll wear it.
