Lea Michele attended the 2017 Billboard Music Awards wearing a hypnotising floor-length gown. From the back, the black David Koma dress is as simple as can be. The front of the dress, however, features eye-catching diagonal mesh cutouts. Due to this sheer element, Lea wore a pair of high-waisted briefs underneath. The dress also benefits from an interesting neckline consisting of unexpected halter spaghetti straps in the front.
