And now , one high street store have created a pair of bottom-boosting jeans that promise to give you a derriere to rival the reality TV star . Debenhams has unveiled a £45 pair of bottom-boosting jeans designed by Jasper Conran . MailOnline 's Hanna Flint pitted the enhancing jeans , right , against her regular jeans , left . Debenhams has jumped on the derriere enhancing bandwagon by giving customers the chance to enhance that all-important asset with a pair of £45 jeans . The new denims , designed by Jasper Conran , can add up to two extra inches to your derriere and have proved an instant success for the high-street chain . According to the store , the Shape Enhancing Jeans are said to be flying off the shelves , purchased by women looking for a more shapely figure . FEMAIL put the jeans to the test to see if they really can give you a pert posterior a la Kim or whether it 's all just a clever gimmick .

The secret to the new jeans ' success ? A clever combination of cheek-enhancing cut , expert tailoring , and heavier denim strategically built in to give extra bulk and curve , promising to turn a shapeless bottom into rear of the year . Control panels at the front also claim to flatten the tummy to emphasise the effect , while the position of the darts in the denim promise to give a flattering hourglass effect . Debenhams also say the jeans give a significant 20 degree rise in overall curvature to the rear . Speaking about the jeans , a spokesperson for Debenhams said : 'Pictures of curvy famous women , from Kim Kardashian and Nicki Minaj , to Pippa Middleton and Carol Vorderman , have helped women with prominent rears realise they have a gorgeous fashionable asset to emphasise , rather than minimise . 'Of course it is a little more difficult for women with a slimmer , straight up and down silhouette . The only solution used to be an expensive gym membership and weeks of working out , but now buying a pair of shaping jeans can offer a wonderful , instant booty boost . ' The jeans promise to give a significant 20 degree rise in overall curvature to the rear , which Bianca London , 25 , tested out ( left : regular jeans , right : bottom-boosting jeans ) According to the store , the Shape Enhancing Jeans boost bottoms thanks to a clever combination of cheek-enhancing cut , expert tailoring , and heavier denim strategically built in to give extra bulk and curve . So what did our testers think ? Jenny Kershaw and Bianca London were impressed . Jenny said : ' I ca n't say I 'm now the proud owner of a behind to rival Kim Kardashian but I like the lift that the jeans give . Everything is more defined and pert - and for £45 , that 's money well spent . ' Bianca added : 'The quality was really impressive and much more fitted and comfortable than my regular jeans , I think these would make a good investment piece and staple item in anyone 's wardrobe . ' Hanna Flint , however , would n't waste her money . ‘ I actually think my bum looks better in the first pair of jeans ! ' , she said . 'The darker colour and shape seems to give my rear more definition and lift while the other pair seems to flatten it . '
