The 26-year-old businesswoman wowed in the racy top as she showed off her cleavage and cheekily exposed her black bra.
Luisa, who is mum to daughter Dixie, teamed her top with a pleated leather mini skirt and towering peep-toe black heels.
The brunette managed to find an outfit for her night out partying, despite admitting on Twitter earlier in the day that she couldn't find anything in her wardrobe! She tweeted: "Nothing to wear tonight."
But Luisa made the most of her night, first of all hitting the UK Lingerie Awards held at the Freemasons Hall in London's Covent Garden.
Her risqué but glamorous outfit certainly kept in theme with the awards bash!
The entrepreneur then showed her support for the Stroke Association by attending a charity fundraising night held at Professor Green's INK LDN club.
Luisa posed for the photographers in a patterned black and white shawl with a furry trim.
The TV starlet partied alongside Made In Chelsea star Ashley James, who also wowed in a metallic gold dress. The pair enjoyed music sets from the DJ as well as grapefruit cocktails all night.
After enjoying her second party, Luisa was later seen heading into popular celebrity hotspot, Nobu restaurant in Mayfair, with a group of friends. She sure knows how to party!
Luisa, who has been busy launching her Bakers Toolkit brand, always looks glamorous at red carpet events, but she recently admitted to Reveal that people would be surprised at how unglamorous she is at work.
"Three new people started with me recently who watched the show and I think they're probably a bit shocked how unglam I actually am," she told us. "I don't want to be sitting in a skintight dress at work. I rock up in ripped jeans, Converse, a t-shirt and no make-up. I do have a pink leather chair though and a sparkling calculator!"
