It was a big fashion night in London, but not every fashionista dominated the red carpet. While we normally love the looks from this week's offenders, their red carpet missteps at The British Fashion Awards earned them a spot on our list. Check out the lackluster looks that Rihanna, Victoria Beckham, Tom Ford, Rita Ora, and Lily Allen donned to attend the ceremony. And we'll leave it to you to decide who you think is the worst fashion fail this week!
