With her deep crimson locks and classic girly-girl style, Ariana Grande is easy to spot on the red carpet. The super-bubbly "Victorious" actress has established a signature style with sweetheart-neckline dresses, full skirts and lots of pastels. Like her music, the budding fashion icon's looks are feminine and pretty -- with a slight retro edge.

The future star of "Sam & Cat", who will play Jennette McCurdy's roommate in the upcoming Nickelodeon show, may be new to the role of the leading lady, but she's been a style star for years. Click through the photos below for 25 of her best looks. Plus, check out Jennette's style evolution to see how the two co-stars' styles compare!
