We pinky promise to make a difference. A gut-wrenching stat: Every 3 seconds a girl is married before she turns 18. Starting today, through #DayOfTheGirl on October 11, post a picture of your ring finger using #VowForGirls. 💍 When you post, our team at TheKnot, along with partners crateandbarrel and peninsulahotels will donate $1 (up to $50K) to vowforgirls to help end child marriage. 📷: jdkanee
