No pop phenomenon would be complete without a foray into fashion accessories for the fans.
In 2010, Justin Bieber launched a unisex fragrance called My World. Instead of coming in a bottle though, it was infused into dog tags and wristbands. What a visionary.
Justin has also released limited edition glasses to commemorate the release of his 3D Never Say Never film.
The Baby singer has also designed a line of nail varnishes in shades such as One Less Lonely Glitter (lavender), Prized Possession Purple (grape), Give Me The First Dance (silver), and Step 2 the Beat of My Heart (heart-shaped glitter).
