This is not the way to mix flowers and leather.
The 20-year-old judge paired a rather dowdy floral print Topshop dress with a leather jacket, and it was all sorts of jarring.
The dress was just too cutesy, and clashed with the sleekness of the leather jacket and the sky-high pumps.
It's like Demi couldn't decide if she wanted to be sweet or steely, and instead ended up looking totally confused.
On a positive note, her wavy dark hair and smoky makeup looked stunning!
