You would think from just looking at her that it must be Coachella or something, right? People dress like assholes at Coachella. Vanessa Hudgens has done a lot of asshole Coachella dressing.
What elevates this to asshole level is that gauzy ...robe? (Is it a robe?), a completely unnecessary addition to the outfit that serves no purpose but to make a point – only an asshole would wear it.
