Cinderella 's wardrobe may be brimming with ornate glass slippers but it 's her classic hour-glass figure women are lusting after . The new Disney film , starring British actress Lily James in the title role , has helped spur on a revival of the shape-shifting garment according to The Sunday Times . The new trailer for the rags-to-riches fairy tale sees 25-year-old Lily flaunt an enviably tiny waist thanks to the help of an icy-blue corset dress complete with floor-skimming puffball skirt .

While online auction website eBay has reported sales of the more modern corset rise by 54 per cent since December . Esher-born Lily , who is dating former Doctor Who star Matt Smith , 32 , recently hit back at claims that movie makers had digitally altered her figure . She says her minuscule waist is achieved by wearing an ultra-constricting corset and by consuming a liquid diet . Models stormed the catwalk at Alexander Wang ( left ) in simplistic corset waist bands while tight-fitting prom dresses ruled the runway at Stella McCartney ( right ) last month . Lily told E ! News : 'When [ the corset ] was on we would be on continuous days , so we would n't stop for lunch or a lovely tea —you 'd be sort of eating on the move . 'In that case , I could n't untie the corset . So if you ate food it did n't really digest properly and I 'd be burping all afternoon in and it was just really sort of unpleasant . ' I 'd have soup so that I could still eat but it would n't get stuck . ' But it 's not just on the big screen where corsets are making a comeback . The restricting bodice , which helps boost breasts , banish muffin top and slim the tum , has featured on the catwalks of Stella McCartney and Alexander Wang this season .

' Katie , whose clients include the supermodel Kate Moss , says the Jessica Rabbit-type body shape is back in fashion . 'Suddenly we 've got Kim Kardashian on the scene with her tiny waist and big hips - it 's amazing to have someone with that kind of figure be popular again - she 's allowing us girls with curves to get back in there a bit .

The celebrity-approved craze is known as waist training and involves completely modifying your figure and posture by restricting it . Trim-tum seekers must wear the corset for short periods of time , gradually increasing use to achieve desired results . Some people even sleep in it . However , health experts have warned of the dangers . Mary Jane Minkin , clinical professor of ob-gyn at Yale School of Medicine , told Women 's Health : . 'Medically , it doesn ’ t make sense that cinching your waist tightly will make it permanently smaller . 'Once you take the garment off , your body will return to its usual shape . 'It ’ s also uncomfortable , restricts your movements , and if you wear it really tight , it can even make it difficult to breathe and theoretically could cause rib damage . '
