Jen Aniston - pretty in pink?

Not according to fashion critics.

The actress, 41, mixed up her red carpet look Sunday at the Paris premiere of The Bounty Hunter, stepping out in a pink silk strapless Christian Lacroix Haute Couture gown.

But called it a prom dress "gone bad ... We're just not that into it, Jen."

An E! News fashion critic wrote that "as much as we think mixing it up is better than playing it safe, sometimes taking a risk can go awry and, well, this one did."

So why didn't it work?

"To pull off a Lacroix gown, you need tons of attitude, otherwise the dress wears you rather than you wearing the dress, which is precisely what's happening in this case," according to "Considering her gorgeous gams, we're surprised Aniston would pick a dress that hides most of her figure and generally doesn't look very flattering. Also, while a bold colour can look like too much if you have a dramatic hairstyle and tons of accessories, Jen's minimal makeup and pony tail just don't look high-impact enough."
