Before you blow your cash on a box set of 30 Rock, indulge in some guilt-free shopping: In May, an army of designers, including Tommy Hilfiger, will sell orange-themed goodies — bracelets, tees, wallets — to raise money for the Nancy Davis Foundation for Multiple Sclerosis. It's part of a new campaign, Orange You Happy to Erase MS (aw!). Your dollars will help fund research for the disease, which affects twice as many women as men and can cause complete paralysis. "This disease is affecting too many women in their prime," says Nancy Davis, who has battled MS for 17 years. Just go to erasems.org and start shopping.
