Luisa, 25, wore the sleeveless number with flared skirt and cutout detail to the Bloggers Love Collection fashion show in London and she definitely turned heads.
The mum-of-one, who made it to the final of this year's Apprentice, teamed her dress with a black pair of statement studded platform heels.
Luisa posed for pictures outside The Penthouse before heading inside and also carried a black clutch bag. She kept her long hair in loose curls and topped off her look with seriously smokey eyes. Gorgeous!
Fans had been asking Luisa if she was among this summer's Celebrity Big Brother line-up. But earlier in the evening, she put paid to the rumours.
Taking to Twitter, Luisa told fans: "Guys I'm not going in Big Brother. I'm sorry to disappoint but I have a business to launch in 8 weeks!! X"
Luisa is preparing to launch Bakers Toolkit, the product she created on The Apprentice.
