Armed with little more than a sheer lace Houghton dress and a bra and high-waisted briefs, Selena Gomez [1] took the stage Thursday for the WE Day celebration [2] in LA. Despite the naked dress, Selena still seemed oddly covered up — let me explain. Relative to the similar dresses we've seen when the whole trend [3] took hold on the red carpet in 2015, most of which were worn (or at least made to appear so) without undergarments at all (Jessica Stam, we're looking at you [4]), Selena looks pretty clothed, especially when you factor in the thigh-high leather boots. But don't just take my word for it — read on for a glimpse of the outfit in action.
