It's not what you think.
While the title may throw you off a bit, don't worry -- you don't have to run to your closet and try on any clothes. Instead you'll get a chance to watch sisters, Niki and Gabi go toe to toe in this challenge. By using a spin wheel the two will spin and whatever the arrow lands on they each have to choose the perfect outfit.
While the title already gives any secrets away, you have absolutely no clue what each sister is going to choose. Just know it's going to be tough choosing the winner, but it's up to you. You can either be Simon or Paula from American Idol, but if you're Simon -- try not to be too hard on the girls. Keep scrolling to check out the video below and may the best sister win.
Who do you think chose the perfect outfit for graduation?
