Ariana Grande tops fashion fails list with bizarre onesie

It's been a rough week for Ariana Grande.

First, the pint-sized popstar was named the second-most hated celebrity in America by Q Scores, the company that polls Americans on their opinions about things like brands and celebrities, and now she's landed on our fashion fails list this week for her disastrous airport style.

The 22-year-old songbird landed in Tokyo and exited the plane in an outfit that was much better suited for a child than a major superstar. While her look was definitely a mess, she wasn't the only celebrity to rock an outfit this week that raised eyebrows. Rihanna and Rita Ora were both double offenders -- with not one, but two fashion fails each -- and Nick Jonas also landed on the list.

See all the wild looks above!
