Amidst all the fabulous craze of Fashion Weeks around the world, Donna Karan has taken time out of her busy schedule to back an online company
that makes it easy for people to host parties for good causes.

Last week, TONIC launched a site for anyone who wants to throw a party with a purpose,and is looking for an easy way to send out and manage invitations. Tired of all those e-vites, pinggs, etc? Well now there's a more sophisticated way of getting the word out about your next big charity soiree.

TONIC allows you to create your own event page, set your fundraising goal, and invite all your friends to donate and boogie down with you! It's perfect for your autumn fundraiser or "no gift" birthday party. And the best part is, TONIC tracks all the impact from your party automatically.

Petra Nemcova has already hopped on the TONIC bandwagon. (Check out her snazzy invite above for her Happy Hearts gala!)So whether you're looking to throw a Halloween party to benefit less fortunate children, or set up a mani/pedi night with the girls to prevent domestic abuse, check out TONIC to help you do good while still having a wild time with all your best buds!
