The Global Citizen Festival is a big concert designed to “bring awareness and action to issues of world poverty and sustainability,” which is great but also might be somewhat undone by the carbon footprint on that bad boy. Then again, I guess that could be true of anyone — Cate Blanchett’s outfit-recycling vs. her international red carpet appearances, for example — so maybe I should be a tad less cynical and just enjoy an assemblage of celebrities — and the fact that Sofia Carson, for one, has more stages on which to bring the fashion thunder.
