Shiffon Co on E! Online: You Definitely Missed the Ring on All Hollywood A-Listers Right Now

The expression "pinky promise" is taking on a whole new meaning.

Hollywood A-listers are bringing back the sacred vow, but instead of hooking fingers, they're wearing rings—and you probably didn't even notice. The accessory represents a pledge to empower women, and we've seen it on everyone from Emma Watson to Nicole Kidman. And while these leading ladies are taking a subtle stand—the ring is a dainty, adjustable piece comprised of two stones— the impact they're making is enormous.

Here's what you might've missed.

Emma introduced the world to Shiffon Co., a company founded by Harvard and Stanford undergraduates, during the eco-friendly fashion marathon that was her Beauty and the Beast press tour. Her Instagram feed served as both our fashion fix and an education in environmentally conscious dressing. Somewhere in between the Oscar de la Renta bustiers and Givenchy gowns was a tiny ring with a big message. Emma posted: "Half the profit from Shiffon's pinky ring collection and 10% of profits from all other Shiffon products directly fund seed grants for female entrepreneurs and companies that promote the well-being of women."
