FIND YOUR STYLE RULES — AND HERE ARE MINE

SARAH HARRIS, 39, is deputy editor of vogue and one of the most influential women in fashion. WHILE there are no hard-and-fast rules to dressing as you age, there are certain considerations worth noting. After 15 years working for Vogue, here are six I’ve gleaned from fashion’s most stylish older women: 1DRESSING

well comes entirely from knowing what suits you and your body type, which of course can change dramatically over the years.

The first thing to consider is well-fitting underpinnings. Unless you’re a lithe twentysomething, clothes rarely look

good on bad underwear-, so get measured and stock up on Spanx, which contour, lift and shave off inches.

2 GOOD tailoring is a smart investment. A blazer has the power to make almost anything look pulled together. I particularly like British brand Connolly and Alex Eagle — her bespoke suits will last a lifetime (alexecyle.comk). I have long lived by the mantra 'buy less but buy better tailoring, better details all the more.

3 HAVING said that, I would rather replenish my stock of mid-price white T-shirts more regularly so they stay whiter-than-white, than buy one expensive one. The men's T-shirts at Gap are excellent. Or you could try Cos (cosstores.com). 4 DON’T avoid colour entirely. It’s all too easy to go for an ‘invisible’ oatmeal palette as you age. I’m not suggesting going all-out in brights, but try warm shades that lift your complexion. I love khaki and dusty rose pink — never pastel, which can often look cheap and be ageing. 5THE

best wardrobes have uniformity. It’s far easier getting dressed when most things go together. Figure out a palette that works for you. I love navy, tobacco and white. Buying several pieces in this palette means you end up with multiple outfit combinations. 6WHEN

it comes to trends, especially prints, apply sparingly. Styling nuances are enough of a nod. I love the idea of a plain sweater with a patterned scarf knotted at the neck to add flair.
