Hot! or Hmm...: Beyonce's Herve Leger Gown

I've admitted to suffering from Herve Leger overload before--it seems every celeb opts for the short tight cocktail for club events. But leave it to Beyonce to wear an alternative:
She rocked a grey banded Herve Leger gown for jeweler Lorraine Schwartz’s dinner party in NYC a few days ago.
Hot or Hmm?
PS Dawn had the following to say about Herve, "I have like five Herve Leger dresses, and people tell me all the time, 'Chill out with the Herve!' But I say wear what the heck you want...it fits curves great. It sucks in all the excess, so I say as long as you're killin it...rock it!"
