It should come as no surprise that our favorite industry insiders  keep up with the latest trends. And, yes, these days, that includes pouring buckets of ice water over their heads to support the ALS Association . And, being that some of Instagram's chicest stars also happen to be downright hilarious (Cara Delevingne, Suki Waterhouse, and Nicole Richie , to name a few), you can expect their videos to be pretty crazy too — especially when Gisele Bündchen challenged Anna Wintour to the task — and Anna came through!
While we can trust Anna to donate to the cause, we love that she completed the challenge along with Donatella Versace , Vogue Japan editor at large Anna Dello Russo, and more stars , models, and even stores that are infusing the ice buckets with a bit of style — while bringing awareness to a very important issue. (Take note of what they're wearing to get wet!) But, don't forget the motive behind it all, because even though these videos may put a smile on your face, supporting the ALS fund is sure to brighten your day.
