Sisters are spectacular! They can be your biggest cheerleaders, your most trusted confidants, and your much-needed fashion advisors (as long as they’re not stealing your clothes!). But sisterhood can also be complex: full of rivalry, jealousy, and not-so-friendly competition. From pop culture sensations like the Kardashians/Jenners to civil rights activists Coretta Scott King and Edythe Scott Bagley to tennis superstars Venus and Serena Williams, these sisters—and so many others throughout history—have not only impacted art, culture, and society, but also illustrate the unbreakable bonds of sisterhood.
