This is epic. You probably know all about the ALS #icebucketchallenge that's sweeping the country right now -- hundreds of your Facebook friends and countless celebrities have taken part! We've watched our favorite models accept the challenge and over $13 million has been donated to the ALS Association so far... but this one might just be our favorite. Vogue's editor-in-chief Anna Wintour was nominated by her daughter Bee Shaffer, and she took the plunge!

Wintour nominated Roger Federer and Dominic West and family to take part in the challenge next, and obviously still looked flawless, even soaking wet. Whether you've been challenged or not, you can donate to the ALS Association at!
