Beyonce Works Sleek White Dresses For Humanitarian Day Performance

The United Nations might be an unlikely place for a concert, but leave it to Beyonce to transform the U.N. into a full-blown music video shoot... AND do it all for a good cause. The star visited the offices on Friday to help raise awareness for upcoming World Humanitarian Day, as well as shooting the video for her single "I Was Here." The video will debut in conjunction with the event on August 19, but luckily for us, we don't have to wait a week in order to ogle Bey's amazing outfits. In typical Beyonce fashion, she worked not one but two chic white dresses. She arrived at the U.N. in an Alexander McQueen bell-sleeved dress (complete with a peplum waist and Ruthie Davis heels, nicely done!) and later changed into a glittery Marc Bouwer ball gown for her performance. With a cutout neck, sleeve detail, and statuesque silhouette, the dress is major without being over the top and attention-grabbing without being flashy. In other words, it's a study in contrasts that totally works.

Not only did Beyonce keep things consistent fashion-wise with same color scheme, long sleeves, and body-con cut, but stuck with a similar beauty look throughout the night as well. We love how the slick ponytail and natural makeup keeps things fresh and lets ALL the focus remain on her outfits (and amazing voice, obviously). Now that we have a sneak peek at what to expect when the "I Was There" vid finally drops on Monday, it'll make the waiting time a little bit easier. Until then, get even MORE Beyonce by checking out her World Humanitarian Day message here.
