Even celebrities go through an awkward phase, hitting the red carpet with orange spray tans, ratty extensions and questionable outfits.
And several stars overhauled their look in a major way this year, whether it was changing their makeup, wardrobe, hair or even attitude.
Miley Cyrus, 19, ditched her nose piercing and undershirts in favor of chic designer ensembles and refined makeup.
"Even on off days, Miley wants to talk all things glam," her makeup artist tells Us Weekly.
Another standout is Taylor Swift who three years ago told Us that her favorite dress is "one that can be paired with cowboy boots." Now the singer, 22, prefers gowns by Reem Acra and Elie Saab, with Christian Louboutin pumps.
