Personal stylist Rachel Zoe has worked with the likes of Nicole Richie, Debra Messing, and Jennifer Garner. She's even coming out with her own lifestyle newsletter. Zoe, who also has her own accessories line, recently Twittered about a particular shade of nail polish that she recommends for warmer-weather manis and pedis.

But, there's more to the story than just a nail polish plug. Find out the mystery shade, along with a reason you should feel all warm and fuzzy about making the purchase, right after the jump.

According to Zoe's Tweet, "Regarding the nail polish queries, my shade preference for the Summer is . . . OPI's Bubble Bath ($8.50)!" And thanks to OPI, for every bottle of this sweet candy pink shade sold in July and August, a portion of the proceeds will go to Look Good . . . Feel Better, a program that assists women coping with alterations in their appearance as a result of cancer treatment. Sweet nails for a sweet purpose. I can go bananas over that.
