This week we meet Lucy Govan, a 25-year-old tomboy who feels that she is just too big to be beautiful. Working in rural Tunbridge Wells, Lucy struggles to feel sexy or womanly; something that is not helped by having to heave around heavy sacks of horse feed for her day job. At 5'11 Lucy feels like a giant and she hates her chunky legs and size 8 feet. She'd never consider wearing a dress, but desperately wants to look and feel more feminine. Lucy is hiding a burning ambition; since an early age she has dreamt of being an actress and even managed to get a scholarship to a prestigious drama school. But she lost her confidence to stand up on stage, and put her acting dreams on hold. Luckily Gok's going to be waving his scissor-shaped wand and help turn Lucy into a stylish Cinderella – no plastic surgery allowed. But if he's going to get Lucy looking and feeling good with her kit on or off, first he's going to have to get her comfortable with looking at her body in the mirror again. Gok knows that when you're not feeling your best is when you most want to hide – but Lucy's negative body image is making her blow things out of all proportion. So he's lined up a bevy of bare beauties to show Lucy that she really isn't as big as she thinks she is, and her 40 inch yummy tummy is perfectly proportioned. Having got Lucy smiling again the next step is to get her realising that she has real star quality, and what better way than to make a huge photograph of her in just her undies top of the bill at her local theatre? With Lucy's baggy outfits receiving the thumbs down from the crowd, she's shocked – and happy – to hear her audience praising her proportions and giving her bangers a big round of applause. With Lucy's skanky old undies consigned to Gok's garden vacuum, it's time for her to find something that will hitch up her hooters and flaunt her figure. With a full style makeover and a massive confidence boost, Lucy's oozing sex appeal, but will it be enough to convince her to lay herself bare for a sultry naked photoshoot and then wow the crowd and do herself proud on Gok's runway?
