Talk about a cause to shop: Elizabeth and James teamed up with Shopbop to create an exclusive necklace, which alone is reason to celebrate, but how about the fact that 50 percent of the proceeds will benefit the Breast Cancer Network of Strength? Now that's reason to buy!

Available online starting Sept. 15, the dainty silver Y-chain from Mary-Kate and Ashley Olsen's fashion line features a bronze leaf charm and provides just the right amount of boho charm to pull off a Woodstock-worthy ensemble.

More in the mood for instant, but still charitable, gratification? Lisa Stewart designed a pink leather bracelet with a silver or gold "Survivor" tag; available now at Los Angeles celebrity hot spot Kitson for $95; with fifty percent also going to the above charity.
