Recently actor Jaden Smith, son of Hollywood actor Will Smith, took the internet by storm when he appeared as the face of a womenswear fashion campaign for Louis Vuitton. His appearance sparked conversation about gender fluidity, gender stereotypes and changes in fashion.

In fact, Jaden has tackled the issue of gender fluidity and defying gender norms before. He has been a long advocate for genderless attire and has previously stepped out in women's clothing, according to Out magazine. For example, last year he went to prom with "Hunger Games" actress, Amandla Stenberg as her prom date and wore a dress.

He's also tweeted about his shopping trips to buy women's clothing.

Aside from Jaden, the fashion world has always taken chances on what's considered socially unique and unacceptable. In some of these more recent campaigns you can see a spirit of inclusiveness, and some unexpected faces.

Last year the fashion world came under fire when a 14-year-old female model became the face of Dior. The decision to include a young teenager in a high fashion campaign sparked debate in the fashion world about hiring young models.
