Our favorite stars dazzled on the orange carpet before the ACM Awards in steamy Las Vegas Sunday night. But out of all the glitz and glamour, Sugarland's Jennifer Nettles impressed us the most with this form-fitting sparkly number. Nettles is our pick for ACM's Best Dressed. See our honorable mentions after the jump.

Kellie Pickler is gorgeous in gold, while Montgomery Gentry's Troy Gentry sure does clean up well in this silver suit. They're our Honorable Mentions for ACM's Best Dressed.
