Experimenting with the current 90s trend, the pop star wore a pair of black leather dungarees over a plain white tee. A pretty brave look, but we think she pulls it off – though we can imagine she's a bit hot in leather!
Keeping with the monochrome theme, she added a pair of white creeper shoes, which featured a black platform and laces.
However, Jessie did inject a pop of colour with her bright Barbie pink bag – ideal for carrying around every day essentials.
Other accessories to finish off her ensemble were a dainty gold necklace that reads "Jessica" and a gigantic pair of hooped earrings.
As for the beauty front, the former The Voice judge, wore her black locks tied away from her face - while a few curls were left loose at the front to soften the 'do.
While most of her make-up was kept simple, with a flawless complexion and a slick of mascara, Jessie coloured her lips with a gorgeous wine hue.
Working perfectly with the rest of her look, we love this bold pout and if you fancy copying, try out MAC's Hang Up lipstick (£15.50) – a creamy formula that will keep your smackers soft, as well as delivering an intense colour.
As well as looking styish, Jessie is busy on the music front too – she recently announced she was teaming up with Ariana Grande and Nicki Minaj for the tune 'Bang Bang.'
And with a new album on the way, there's plenty more Jessie action to come!
