In celebration of Sisters Day

In celebration of Sisters Day

On the first Sunday of August each year, countries around the world celebrate the special bond of sisterhood. This year, Sisters Day falls on August 1.

Whether they are biological sisters, stepsisters, half-sisters or even friends with a strong, sisterly connection, sisters of all kinds share a unique bond. Sisters come in all shapes and forms, and Sisters Day is about celebrating them all!

There are many examples of US sisters who have achieved great things – sometimes together, and sometimes apart.

1. Venus and Serena Williams

Growing up in the suburbs of Compton, California, the Williams sisters also have three half-sisters, Yetunde, Lyndrea, and Isha.

Venus and younger sister Serena both started playing tennis at a young age, when their talent for the sport quickly became apparent. Between 2000 and 2016, the pair collectively won 12 Wimbledon singles titles, while also winning several doubles titles.

After the French Open in 2002, Venus and Serena were ranked No. 1 and No. 2 respectively, making it the first time in history that sisters had occupied the top 2 singles spots in the world rankings.

2. Mary-Kate and Ashley Olsen

The Olsen twins have been in front of the cameras since they were just nine months old, when they were cast in the ABC sitcom Full House. In order to comply with child labor laws, the sisters took turns playing the role of Michelle Tanner.

From starring in their own TV and video projects throughout childhood, the sisters transformed themselves into fashion icons as they grew up. They launched their own couture fashion label, The Row, in 2006.

3. Beyoncé and Solange

Born in Houston, Texas, Beyoncé Knowles-Carter and Solange Knowles both looked set for stardom from a young age.

When she was just 16 years old, Beyoncé found fame with Destiny’s Child, before embarking on a successful solo career which has seen her sell over 100 million records worldwide. She is one of the best-selling musical artists of all time.

Younger sister Solange is also a singer and former backup dancer for Destiny’s Child. In her early years, Solange wrote songs for the group before embarking on her own solo career. Beyoncé and Solange are the first sisters to have both had No. 1 albums.
