Matilda and the Ramsay bunch undertake a major fashion challenge - to give Jack the ultimate makeover and turn him into the coolest boy at his party! Holly and Megan team up with Rebeka Roy, one of the UK's top fashion stylists, and Tilly gets down to work cooking a super-stylish pre-party dinner. On Tilly's food red carpet are some of the most fashionable dishes around - her brilliant boa buns, spiralized noodles with a spicy peanut sauce, and accessorised boba tea. With Rebeka's expert help Holly chooses some fantastic 'looks' for Jack to model and before they eat Jack gives them a catwalk preview of his choice - will it get a stylish thumbs-up or be deemed a fashion disaster?
