The Met Gala has become one of the biggest fashion events of all time, and in the past decade more and more music artists have dominated its red carpet, proving that they are willing to push boundaries further than any model or actress would be willing to go (a few examples include Madonna's backside-revealing Givenchy ensemble and Beyoncé's latex look, also by Givenchy, from last year's event and Solange's futuristic Giles gown from 2015).

Here, five of music's best Met Gala looks that show both risk and reward.
