If you have a snapchat or have been following NYFW on Instagram, two faces have been dominating many catwalks, and these two faces just happen to be sisters. This week, Gigi and Bella Hadid have been dominating many designer runways, including Jeremy Scott, Diane von Furstenberg and Tommy Hilfiger.

These two sisters have been the new "It Girls" of the fashion world over this past year. Both women have racked up more than 1 million followers on Instagram, and the love doesn't stop there.

Gigi and Bella are the faces of many prominent fashion and beauty brands such as Maybelline, Topshop and Ralph Lauren Denim & Supply.

With the help of social media, Gigi and Bella have taken over the fashion world and receive exceptional praise in the media.

Their mother, Yolanda Foster, was once a model herself, and she often praises her gorgeous daughters for their hard work and perseverance.

This isn't the last time we will see this dynamic duo light up a catwalk this week. Not only did Gigi open the show for Jeremy Scott, but Bella got to close the show.

Talk about girl power. We are extremely jealous of these talented ladies and wish them the best of luck this week.
