First, Luisa was pictured wearing a pretty and floaty floral frock while attending a launch party for the new Tim Drummond & Phil Hawksworth health book, The 3030 Body Blueprint, at the exclusive Soho Sanctum Hotel in central London.
The mum-of-one's dress featured mid-length sheer sleeves and she clinched it in at the waist with a brown plaited belt. Luisa topped off her outfit with a co-ordinating pair of heels.
One party - and dress - was not enough for this businesswoman however!
Later, following an outfit change, Luisa was photographed wearing a teal coloured dress, which was more figure-hugging than her first.
Sporting sheer cap sleeves and a plunging neckline, this little number seemed more suitable for the launch of new Russian vodka bar Ruskis Tavern.
She matched her dress with a black pair of peep-toe heels and carried a black clutch.
Professional cake master Luisa, who showcased her new brand Bakers Toolkit earlier this month, hung out with her good friend, Capital FM DJ Greg Burns, at the launch in Kensington.
But although it was very much a vodka-based event, Luisa stuck to soft drinks as she had decided to be the designated driver for the night.
Sharing a picture of Greg raising a shot glass, Luisa told her fans on Twitter: "Vodka and cavier @RuskisTavern with @GregCapital, no vodka for me though - I'm driving!"
