Joining the likes of Rita Ora and Rihanna on the red carpet, the starlet showed how to pull off two of this summer's trickiest trends - a crop top and a lime green hue!
Jessica went for a white bandeau top that showed off her tanned bod to perfection but while it may have been skimpy, she kept things classy by pairing it with a high-waisted, knee-length skirt.
The A-line number featured one of the shades du jour - a zingy green! Jessica's paler pastel version ticks off the trend but it's a whole lot more wearable than an OTT 'need your sunnies to look at it' shade.
She kept her jewellery minimal and finished off her look with printed pointed courts.
Jessica, we salute you!
