Decoded: A-List Sisters And Their Signature Styles

These sisters have gone in completely different style directions...

Isn't it funny how growing up and being forced to dress the same as your sister can actually cause you to go in completely different directions, style-wise, as adults?

From Beyonce and Solange to Kate and Pippa, each of these sets of famous sisters has got their own USP, or unique styling point, going on (see what we've done there) , so let's examine the evidence, shall we? 

Beyonce Knowles USP: Queen Bey loves a fiercely glam mix of jewel-encrusted stage outfits, sporty leather daywear and barely-there red carpet dresses, with favourite labels including Givenchy, Chanel and Topshop. Trademark Pieces: Thigh high boots, letterman jackets, and black leather erry-thang.

Solange Knowles USP: While Beyonce loves black leather for day, Solange’s wardrobe couldn’t contain a greater rainbow of colours. In sharp tailoring or maxi silhouettes, she always looks quirky and seriously cool. Trademark Piece: Colourful co-ords. Would Never Wear: Nude courts.

Kate Middleton USP: Kate loves a dress coat and fascinator combo, usually whipped up by Alexander McQueen designer Sarah Burton, or on the high street, Reiss. Trademark Piece: Those LK Bennett nude court shoes. Would Never Wear: Just jewels.

Pippa Middleton USP: P-Middy is a classic Sloane ranger and Temperley’s number one customer. Favouring style over trends, her repertoire consists of ladylike boho dresses and Hobbs casual wear. Trademark Piece: A linen blazer over a cotton day dress, teamed with cork wedges. Would Never Wear: Something too trendy.

Kim Kardashian USP: Body-con. All day, every day. Our Kimmy LOVES a figure-hugging, sheer number, preferably topped off with a billowing silk duster coat. Trademark Pieces: High waist pencil skirts with turtleneck crop tops usually by Balmain or Givenchy. Would Never Wear: Something too sensible.

Kendall Jenner USP: Kendall’s got that whole off-duty model style thing nailed. Her new favourite combo is bleached skinny jeans, metallic lens aviators and a loose silk shirt. Trademark Piece: Cool LA denim. Would Never Wear: Last season’s trends.

Cara Delevingne USP: When she’s not on the red carpet, sporty tees and boyish accessories are Cara’s go-to. She’s now as famous for her laid back approach to styling, as for her supermodel glam moments. Trademark Piece: Slogan tees, high top trainers and beanie hats. Would Never Wear: As a catwalk chameleon, we think she’d try anything once.

Poppy Delevingne USP: Poppy D does boho glossy like no other. She literally goes with the flow at all times, draping herself in chiffons by everyone from Matthew Williamson to Chanel, to Stella McCartney. Trademark Piece: The printed maxi dress. Would Never Wear: Trainers.

Charlotte Dellal USP: Shoe designer Charlotte is the queen of retro glamour. In 40s fit ‘n flare dresses, she always looks polished and simply wouldn’t leave the house without her vintage set curls. Trademark Pieces: Cat eye sunglasses and incredible arty heels, obviously. Would Never Wear: A tracksuit and trainers.

Alice Dellal USP: Alice works a totally different vibe to her big sister. Her look is ripped, raw and rock-worthy – but still luxe. Those biker boots are Chanel, don’t cha know? Trademark Piece: Fishnet tights, black crop tops and studded leather jackets. Would Never Wear: A 40s-style dress.

Amal Clooney USP: When human rights lawyer Amal is at work, she cuts a powerful figure in tailored jumpsuits and two-piece suits by Giambattista Valli and Maison Margiela. In her own time, she’s more experimental and has trialled every trend from flamenco ruffles to gold foil on the red carpet. Trademark Piece: The power suit.

Tala Alamuddin USP: Amal’s almost identical sister Tala knows an IT-bag when she sees one. She’s been spotted working the covetable Moschino milkshake, a Burberry holdall and some adorable vintage trunks in recent months. Trademark Piece: Accessories, accessories, accessories.
