The baking queen, from St Albans in Hertfordshire, attended Hamley's Tickety Toc Launch Party on London's Regent Street and looked stunning in a fitted peach dress.
She teamed the outfit with a cute black belt, matching handbag and heels.
Luisa, 25, took her three-year-old daughter Dixie to the famous toy shop and later posted a super-cute picture of her "princess" fast asleep.
Alongside the picture, she wrote the caption: "@TicketyTocUK thank you for having us. Dixie is now fast asleep after such an exciting morning!! X"
She added: "Had a lovely morning with my princess @TicketyTocUK in Hamleys! Amazing to shop there before it was open and Dixie loves her goody bag!"
Earlier this week, Luisa thanked her fans for their support during The Apprentice and revealed she has 16 investors interested in her baking firm.
