I will be the first to admit that I have a large, somewhat ridiculous girl crush on Demi Lovato. She seems like such a sweet girl, and her style is edgy and girly but in a fun, appealing and relatable way. At just 20 years old, Demi has spent years in the spotlight, gone through a major trauma in the public eye, and evolved as a female before our very eyes. But, recently, Demi has really come into her own in terms of fashion.
