If you have been on Instagram within the last couple of days, chances are you noticed women posting black and white selfies. It's for a social media challenge that aims to both empower and celebrate women of all different backgrounds, shapes and ethnicities. 

Everyone from Khloe Kardashian to tennis' very own Garbine Muguruza accepted the challenge by friends who nominated them.

Although the posts don't require too much to be written in the caption, the photos of these inspirational faces remind the world just how important they are, and also remind women to do better to elevate other women.
