Demi Lovato's style transformation: See all of her best fashion moments!

Demi Lovato's style evolution is one for the books! Over the years, there hasn't been a fashion trend that the star hasn't tried. From blue hair to blonde hair, from punk rock to Grecian goddess, she's rocked every type of look, all while staying true to herself.

Demi first caught our attention in 2008 with the premiere of Disney Channel's original movie, "Camp Rock." Since then, she has grown to become a bonafide rockstar and an advocate for mental health.

In September 2019, she posted an unedited bikini photo on her Instagram that showed off her cellulite, revealing in the caption that posting it was one of her "biggest fears."

"I want this new chapter in my life to be about being authentic to who I am rather than trying to meet someone else’s standards. So here’s me, unashamed, unafraid and proud to own a body that has fought through so much and will continue to amaze me when I hopefully give birth one day," she wrote.

While she also admitted on Instagram that she loves a cheetah print bikini, other styles Demi tends to gravitate towards are edgy pantsuits and curve-huggings gowns with plunging necklines.

One of our favorite ensembles worn by Demi is from 2017, when she stole the red carpet at the Grammy's in a gold see-through dress by Julien Macdonald. That same year, she also stunned at the Vanity Fair Oscar's after-party wearing a custom periwinkle princess-style gown by Monique Lhuillier.

We can't wait to see what future chapters hold for Demi, but in the meantime, we're taking a look back at some of her past looks over years. Check out Demi Lovato's style transformation in the slideshow above and see some of her best Instagram moments from 2019 below.
