Demi Lovato is the lovely new cover girl for the November 2012 cover of Teen Vogue. In her interview, Demi talked about her role as a mentor on "The X Factor," how to stay healthy, how she spends her free time, and dating rumors.

For the cover, Demi wore a pretty white Guess "Mira" blouse featuring sheer long sleeves, geometric cubes, ties at the wrists, a Henley style button-front, and lace detailing. Her feminine top was teamed with a multi-colored skirt by Marc Jacobs. She accessorized with a gold KiraKiracoin necklace, a gold Maya Brenner Designs shark tooth necklace, a gold Stella & Dot long chain necklace, and a gold Jennifer Fisher chain link ring.

Her next look included a pretty floral long shirt dress by Marc Jacobs paired with a belt by American Eagle Outfitters and nude pointed toe pumps by 3.1 Phillip Lim. Demi's jewelry items included Kevia earrings, a Maya Brenner Designs necklace, and a Kelly Wearstler cuff.

Demi also switched into a charming floral dress from her favorite brand Topshop. Her autumn meadow printed dress with fluttery short sleeves was accompanied by gold hoop earrings by Kendall Conrad.

I adore Demi's Guess blouse and her Topshop dress. Which look to you like the best?
