It may not have been her big day, but all eyes were on Naomi Campbell when she stepped out in Givenchy haute couture to the official dinner and ball of Prince Albert II of Monaco and Princess Charlene at the Opera Garnier over the weekend.

The runway queen has been tsk-tsked for upstaging the princess bride in the dazzling gown—not only because she’s wearing white, which is traditionally frowned upon for guests at weddings, but because the dress’ revealing design, with its cutout sides and cleavage-revealing plunge, completely eclipsed the more modest and simple Armani Prive cocktail dress that Charlene changed into for the afterparties.

See, this is the type of look that gets all the men at the wedding reception buzzing as their wives and girlfriends shoot evil glares! 

What's your take on this head-turning gown?
