Don't Miss:

The X Factor judge Simon Cowell called contestant Melanie Amaro “brilliant” and “bloody fantastic,” and the 19-year-old singer deserves every bit of praise. She’s belted out songs by Whitney and Mariah, and she is the only female left in the competition. On tonight’s finals, Amaro will compete for the $5 million prize against Chris Rene and Josh Krajcik. While we can’t wait to hear her sing, we also can’t wait to see what she’ll wear! We chatted with the X Factor style team—hair stylist Ken Paves (left) and makeup artist Kristofer Buckle (right)—to get all the details about Amaro’s style transformation. Find out her secrets in the gallery now.
