Sisterhood

If once the favourite accessory of the young stars on the red carpet was a clutch, or a chihuahua for the most daring ones, nowadays we are assisting to a new fashion phenomenon: sisterhood.

Everything started with the Olsen twins in the 90s: every little girl in every corner of the world started to dream she had a sister, better if a twin one, with whom to share adventures and misfortunes of every kind. In the meantime the two American blondies have grown up, they had a brilliant career and now they've left the space to a new generation of trend-setter sisters.

The latest one to pay homage to the phenomenon has been Olivier Rousteing, who reunited three very glamour couples of sisters for Balmain AW15 campaign: Gigi and Bella Hadid, Joan and Erika Smalls, Kendall and Kylie Jenner.

From cinema to fashion, from music to reality-shows, we analyze the 5 couples of sisters which lay down the rules in 2015.

#1 The Olsen twins

In this list we couldn’t ignore the founders of the movement: Mary-Kate and Ashley Olsen. Born in Los Angeles in 1986, they started playing at the age of only six months and since that moment they've never stopped being under the spotlight. The played in numerous movies about adolescence focused on their likeness and when they grew up they left the big screen to dedicate to fashion. Nowadays they are the designers of a successful brand: The Row, for which they have been awarded Womenswear Designer of the Year from the Council of Fashion Designers of America (CFDA) in 2015.

#2 Elle and Dakota Fanning

Elle and Dakota Fanning are the most promising adolescent sisters of cinema nowadays. Dakota was born in 1994 but she has already played in more than 50 movies between cinema and tv. Elle, born in 1998, started her career playing the younger version of her sister in I Am Sam (2001) and then she obtained roles of growing prestige like in Sofia Coppola’s Somewhere (2010) and Maleficient (2014) next to Angelina Jolie. She has also been the face of miu miu SS14 campaign.

#3 Cara and Poppy Delevingne

They are probably most popular models-socialites of the UK. Rich and beautiful since they were born, they grew up in the posh neighbour of Belgravia in London until Sarah Doukas, founder of Storm agency in London, launched them on the international runways. Cara has become an international icon, she turned the rules of fashion upside down with her grimaces and her lesbian relationships, she's an insta-queen and she recently made her debut in cinema, her true vocation. Poppy is the most rational and traditionalist sister: she's been elected Young Ambassador of the British Fashion Council and in May 2014 she's married her historic partner, James Cook.

#4 Georgia May and Elizabeth Jagger

Daughters of a music myth and a model icon of the 80s, the Jagger sisters couldn’t be anything but beautiful and extremely cool. Elizabeth was born in New York in 1984, eldest son of Mick Jagger and Jerry Hall, while Georgia was born in London in 1992, third-born of the couple. They are invited to the coolest parties in London and they recently posed for the second time for Sonya Rykiel in her AW15 campaign.

#5 Kylie and Kendall Jenner

Daughters of Bruce (now Caitlyn) Jenner and Kris Jenner (before Kardashian) Kylie and Kendall Jenner became famous as co-protagonists of the reality show Keeping Up With The Kardashians, along with their half-sisters Kourtney, Khloé and Kim Kardashian. Together they designed two clothing lines: one for American brand PacSun and one for British giant Topshop. Recently Balmain unveiled the images of the AW15 campaign with them as protagonists.
