Bella Hadid is taking the no-bra trend [1] to the next level. While strutting her stuff on the runway at the Alexandre Vauthier show at Paris Fashion Week on Tuesday, the model showed off her breasts in a sheer blouse. Of course, this isn't the only time Bella has fogged up our computer screens with her smoking hot figure. Aside from her countless runway and red carpet appearances [2], she is constantly filling our Instagram feeds with sexy bikini pictures [3]. See the photos from her NSFW catwalk below.
