American Idol's Carrie Underwood has been getting blamed for problems that already existed on the show, but there are several issues she didn't cause.

Fans first saw Underwood wear the halter-top dress during the Season 4 finale in May 2005. She rocked the look when Ryan Seacrest called out her name as the winner. Bo Bice was the runner-up. Underwood shared some insight on deciding to slip back into the memorable look for the latest “Idol” episode.
