Strong Is The New Pretty is a beautiful series of American photographer Kate Parker: https://www.katetparkerphotography.com/ based in Atlanta, featuring her two young daughters and their friends in photographs overflowing with energy and bathed with the innocence of childhood. Far from the clichés about beauty, these portraits capture these girls as they are, not how females are expected to be.
