On Saturday night in New York, Beyonce appeared at the UN headquarters to perform in support of World Humanitarian Day. For the occasion she wore an exquisite white micro-sequin dress by South African-born fashion designer Marc Bouwer from his pre-fall 2012 collection.

How extraordinarily beautiful is this dress? I think that this is the best she has ever looked. Simple. Sleek. Beautiful. I have said enough.
