After more than 20 seasons, America's Next Top Model has become a hallmark of reality TV shows. The show's creator and fashion icon Tyra Banks has been celebrated for helping build the careers and brands of women of color and other minorities in her career's second act. 

In a Tuesday Twitter thread, Twitter user Aisha Oladapo noted a particular scene in which Banks advises season six contestant Danielle Evans to have the gap in her front teeth closed because it wasn't “marketable.”

The tweet went viral and prompted commentary from other users who, in hindsight, found some of Banks' guidance on the show to be problematic.
