You wouldn't guess that by purchasing a hot pink, lacy lingerie ensemble that, ahem, glows in the dark, you'd be waging war against breast cancer.

But, in fact, October is the month when fashion and beauty forces rally for this cause, offering a staggering number of products to fight the disease. (For the record, the fluorescent undies are by Cosabella.)

So, really, buy a little something.

"I think it is important for everyone to get involved with Breast Cancer Awareness month," says actress Garcelle Beauvais, who's working with handbag designer Patricia Nash on a promotion to benefit the Breast Cancer Research Foundation. "If we support each other and help each other, then together we can find the cure."

Yes, of course you can splurge. A David Yurman pink ceramic and diamond watch has our lust-o-meter shorting out and costs thousands. But shelling out $5 for a great athletic tee at Kohl's helps, too. The Estée Lauder company and its many brands will raise money for the Breast Cancer Research Foundation; at Avon, all net proceeds from special items go back to the Avon Breast Cancer Crusade, and Ralph Lauren's Pink Pony Fund has been supporting programs for screening, early diagnosis, treatment, research and patient navigation for 13 years.

We've combed through piles of pink -- and, by the way, not everything is actually pink -- to bring you the best of the best. You'll look good, feel fabulous and, in some cases, even have a little fun (back to that lingerie), all the while battling the disease that affects so many of our friends and families.

Everything's turning up rosy, wouldn't you say?
