We adore Leighton Meester's fashion sense. We've said it before -- she can pull off just about anything. And that includes Reebok's tennis shoes with a frilly dress and leather jacket -- there are no limits as to what she is able to make look good. However, we're on the fence about this Calvin Klein dress the Gossip Girl star wore to Parson's Fashion Benefit Party.

On one hand, we love that it's architecturally structured, making for a cool, very straight off the runway look. And those shoes are to die for!

But, on the flip side, we're not used to seeing Leighton quite so covered up. We wonder if this dress might work a little better on someone older. With the long hem length plus covered up shoulders, the dress is rather mature.

So what do you think? Is this Calvin Klein dress on Leighton dress a hit or a miss?
