The 26-year-old had no problem squeezing into the red satin garment on Tuesday (25 February) as she attended a lingerie party in London.
Luisa tried on the corset at the Box Of Grey party held at the Sanctum Soho Hotel and was joined by the likes of Made In Chelsea's Spencer Matthews.
Apprentice star and mum-of-one Luisa was clearly tempted by the lingerie on display and couldn't wait to try one on.
Leaving little to the imagination, Luisa posed in the corset while standing in a room full of guests and shared the revealing photo with her Twitter followers last night (26 February).
Captioning the snap, she said: "Loved @boxofgrey last night so seductive & sexy. This corset made by @SianHoffman is AMAZING love it!"
Luisa later added: "I love being laced!"
Also this week, Luisa enjoyed a catch-up with her former CBB housemate Casey Batchelor, and partied with Dappy the week before at the Brit Awards after party.
