Answer:
This is a girls night out party, based upon the familiar white elephant gift exchange. All of the gifts, decorations and refreshments are base upon the color pink.
Some pink elephant parties require that you attend wearing something pink.
These parties can also be used for raising funds for breast cancer and other women health issues.
On-line white elephant party vendors could be approached to display only pink gifts in one of their custom marketplaces, so as to maintain a pink theme.
