She usually opts for a quirky, funky style over girlie glam.

The Price Tag singer stepped out in a tiny metallic dress and high heels making a dramatic entrance at The Roundhouse in Camden.
Simply stunning: Jessie J looked incredibly glamorous in a tiny glittering dress and high heels as she arrived at The Roundhouse tonight
Jessie had her brown locks in curls tumbling down around her shoulders and showed off a bronzed tan.
Her feminine dress not only boasted a
plunging neckline and was partially see-through around her torso – it
was extremely short.
Jessie added a flash of colour with a bright orange manicure and a matching pedicure.
Slipping into something a bit more comfortable: The singer swapped her heels for a pair of trainers on stage at the Glaceau vitaminwater presents 'Jessie J Live In London' event
Well she wouldn't have been able to do that in heels: Jessie was seen running around the stage and at one point was seen on her knees which would have proved tough in her original footwear
While fans might have been shocked to
see Jessie looking quite so girlie Jessie dressed down her outfit
switching her heels for a pair of trainers to take to the stage.
And given Jessie's energetic performance which saw her sliding on her knees it's no surprise she swapped her shoes.
Mixed up style: Jessie rocked the trainers and glittering dress look
