The Ex On The Beach star wowed in a sexy cut out black dress while attending the first birthday party for shoe brand Ego in London on Thursday night (2 June).
Jess proved she didn't need to splash the cash to look gorgeous, opting for a purse-friendly gown from Oh Polly, available for £30.
And the shoes, of course, where from Ego, available for £29.99.
Jess has recently been campaigning on behalf of the Guide Dog charity to stop discrimination of guide dog owners by some taxi and mini cab drivers.
The MTV reality star is a passionate advocate of guide dogs and owners' rights, after her own mother lost her sight around nine years ago.
Joined by mum Debbie, who has a guide dog, the reality star lobbied parliament last week to raise awareness of the issue. She recently told Daily Star: "The thing is staff are just not trained in what do to. They aren't told about the situation or how to deal with it so they just try and refuse you.
"It is hard enough for anyone to go blind as it is without being discriminated against. I can't even begin to explain the extra emotional stress and trauma that it brings."
