Trendy or Tacky: Color Block Overalls?

I want to hate this look but I can't because I love AnnaLynne McCord! She attended the GUESS 1981 Fragrance Launch and wore these navy and white Guess overalls with a peek-a-boo bralette underneath. And it was that sexy little bra and trendy choker that saved this outfit in my opinion. I understand that she had to wear something by the designer since it was their event, so I can't completely fault her for this look. But I can blame Guess for giving the same exact overalls to three different girls at the launch!
