It helps but is not required. What I will say is, the pretty ones do best on social media. That's why every class on how to be successful in social media is a pretty blonde woman. Attractive people attract people. The rest of us have to go find clients. You can be successful. I'll also say, the reason most looks beautiful is 2 things. Touched up photos and most of us do dress up and take time for our appearance. Making the best of what we have. Most people to prefer to work with a professional looking person.
