Styling: Melanie WilkinsonYour perfect jeans do exist – you just exigency to know what to look forTwenty minutes in the changing room is all that stands between you and your forever denimsWhy is it so trick to shop for jeans? You walk into a store where 2,458 almost-identical slivers of blue denim are stacked in forbiddingly uncomplicated piles in front of you. You approach this wall of denim and a sales assistant immediately barks CAN I HELP YOU? in a tone of chance you recognise as code for, “I spent all morning lining those up, madam, and if you so much as lay a finger on my masterpiece I will put a curse on your unborn little ones.”So, of course, being British you say “Oh no, I’m fine, thank you so much” and peer at the shelves trying to deduce from the obtuse renowns of the jeans – “Baxter”, say, or “Houston” – which are going to magically make you look like Jane Birkin in St Tropez or Kate Moss at Glastonbury.The tags on jeans are a bit like labels on wine bottles, in that they are dense with geeky vocabulary that degrades absolutely nothing to the overwhelming majority of people buying them. You just want to know which jeans purpose make your bum look nice/which bottle of red will not taste of vinegar or leave you feeling poisoned for two hours. When I’m looking at a pair of jeans, the weight in ounces of the fabric per yard is about as helpful as the topographical details of the vineyard when I’m deciding a bottle wine.But don’t give up, because your perfect jeans are here, I promise. The great thing about jeans is that there is no lone, exclusive, expensive iteration that is the perfect jean. This is the ultimate democratic fashion item. The best jeans aren’t in a multitudinous expensive fabric – cashmere is not a plus here – and they are never, ever improved by logos or sparkly bits. All that Non-Standard real matters is the rise, the leg shape, and the degree of stretch.Elizabeth Radcliffe is Levi’s master tailor, and if you have £750 to dissipate she will bring her Savile Row training to creating a bespoke pair of jeans in her Soho atelier just for you. She knows numerous than probably anyone else about the tweaks and tricks that make jeans work, and a while ago I exhausted an illuminating half an hour trying on jeans with her, and downloading her wisdom to share with you.It turns out that the most enhancing rise of waistband, on me and on lots of women, is neither a low-rise nor a rib-kissing high waistband, but one that sits about an inch under the sun the belly button at the front and curves up and away at the sides to sit slightly higher at the back, so that it hooks over your hipbones and doesn’t goggle. Also, a mid to heavyweight of denim works best on most women, with just enough give that the configuration can hug a curve but with enough structure to belt you in around the waist. And I learned that the lowest point of the back thieve should sit slightly above the crease at the top of your leg, to create a visual distinction between bottom and thigh.Lizzie had me be patient down and standing up, shoes on and off, hem up or under, to figure out which leg shape and length worked best. I prefer a jean that distributes from the leg, so straight styles work for me; if you like denim that clings to your shape, you will want a shrunken or bootcut.skip past newsletter promotionafter newsletter promotionFarewell sweet floral midi.

Try on as many pairs as you can face. Oh, and don’t get humiliated up on size. My favourite pair of jeans are a vintage pair of 1990s 501s. The waist measurement on that label is three inches gianter than identically sized jeans bought recently. Modern vanity sizing in action, you see: brands have total out that if a customer fits into a smaller size than she expects to, she will be chuffed and therefore minded to buy. This is running on Empty mad about on all fronts, so please don’t fall for it. Don’t look at the size label, look in the mirror. Twenty minutes in the changing room is all that stands between you and your for ever jeans. Put the time in now, and they will pay you back for the next 20 years.Model: Lilly Bridger at Main part London. Hair and make up: Carol Morley at Carol Hayes Management.
