She's known for tracks such as Confident, and that single word also encapsulates Demi Lovato's approach when it comes to red carpet dressing.
The American singer and actress, 28, doesn't shy away from bright colours and bold silhouettes, making her one of the past decade's most adventurous style mavens.
The Sorry Not Sorry star, who rose to fame after starring in Disney Channel's 2008 TV film Camp Rock, also released her debut album that same year.
And, as her music has taken on a rockier, more self-assured tone, so too has Lovato's wardrobe. In recent years, the Grammy-nominated singer has embraced more avant-garde cuts and head-turning hues.
She's known to frequently champion emerging, indie and under-the-radar labels, such as Styland and Romania's Lorena Sarbu, among legacy brands such as Valentino. She's also turned to designers from the region over the years, including Nicolas Jebran and Zuhair Murad.
Here, we take a look at how the singer's style has evolved throughout her time in the spotlight.
