Do you remember summer '09? We wanna go back there every night. Or at least, we had fun going back in time to see the red carpet looks of five years ago in the name of Throwback Thursday! (Sorry, we couldn't resist a One Direction reference.)
We couldn't believe how much stars like Demi Lovato and Taylor Swift have totally revamped their styles since they appeared at red carpet events in the summer of 2009. Some stars' hairstyles have changed as much as their outfits since then: Ariana Grande's hair was bright red! Miley Cyrus' hair was styled long, brunette waves!
