Following some early-on insecurity, the pop star explains, "After a while, it was like, 'What’s the worst that can happen?' I just started being a little more daring with it. It was just knowing my body … is what it is under clothes or outside of clothes."
Although shedding her attire on a regular basis has had a beneficial outcome for the image she's trying to convey, Rihanna admits, "My way probably won't work for most people."
