The artist, the feminist and the model are joining others worldwide to empower women in the marketplace through ethically-themed fashion.
The campaign, called ImagiNation 365, is led by Maiden Nation, an online social platform.
Yoko Ono, Gloria Steinem and Lauren Bush contributed by designing pieces of jewelry that express their vision.
Other designers live in countries including Poland, Afghanistan, India, Argentina and South Africa. Four are teenagers from Grand Rapids, Mich.
Proceeds from the sales goes to causes chosen by the designers, such as helping Japanese girls after the 2011 nuclear meltdown or job training in Haiti.
