A new viral challenge is taking over social media. The Bra Toss Challenge is helping to raise awareness about women's rights, feminism, and sisterhood, according to Elle. It has a similar format to the wildly successful Ice Bucket Challenge that raised awareness and fund for the disease ALS. Instead of dumping a bucket of ice cold water on your head, women are throwing their bras at the camera filming them. If you're participating in the Bra Toss Challenge you must name a woman who inspires you, toss your bra, and then challenge a few of your female friends to take part. Elle is reporting that the challenge was created by YouTube star Lilly Singh on International Women's Day "in support of strong, powerful women everywhere."
