And at this year's V Festival, Jessie J made sure she lived up to her trendy reputation by rocking a monochrome two-piece bralet and high-waist pant combination.
The 25-year-old Price Tag singer performed in her home county of Essex dressed in a tiny black top and shorts and a custom-made white Tyra top from the lingerie brand Lascivious.

Her newly cropped blonde hair was gelled into a small quiff whilst her skin looked radiant applying shimmer to her cheekbones, lashings of black mascara and a fiery red lipstick.
She opted for extra large gold hoops, which colour-coordinated perfectly with her gold-headed microphone, and she finished the ensemble with a black and white leather jacket with gold zips and black leather trainers.
Jessie looked to be enjoying her stint on the Virgin Media Stage at Hylands Park, and it is not over for her yet, as she will be performing the same gig in Weston Park, Staffordshire, on Sunday.

The energetic routine is a trademark of Jessie's who put the same amount of vigour into the making of the video for her new track It's My Party.
The pop princess has recently recruited the services of model Jourdan Dunn who made an appearance in the video.

On a coach heading to V Festival Jessie J was furiously attempting to sign as many photos of herself, which presumably were going to be given away at the event.
She tweeted a photo of a stack of posters of herself along with the message: 'Operation sign as many cards as possible...'
Jessie followed this post with a short Instagram video of scores of youngsters making their way to the V Festival gates at Hylands Park just as a police car drove by.

Also performing on Saturday night, but 163 miles away on the Virgin Media Stage at Weston Park, was Emile Sandé.
The 26-year-old singer, from Sunderland, was dressed in a similar rock-inspired get up, wearing a leather jacket, black vest top, black jeans and trainers.
Her cropped blonde hair was styled into her signature mohawk, and she too donned a shade of red lipstick for the two-day festival, which will also see her perform in Essex on Sunday evening.
