Never underestimate the power of the little black dress. Just ask Sheena, who, with the help of a few friends, started The Uniform Project to promote sustainable fashion and help a good cause.
The mission: wear one dress for one year (don't worry there were actually seven dresses for each day of the week) and raise money for The Akanksha Foundation to send boys and girls to school in India.
The result: 365 incredible styles and $94, 862 or enough to send 263 kids to school. They're already working on year number two and a new dress to change the world.
Now that's pretty powerful.
