In the latest development from her eponymous fashion line, Williams has unveiled a new dress which was created for “everybody and every body”.
The tennis star also features in the video, modelling the exact same piece.
She captioned the post: “We’re having a red hot summer over @Serena. I designed the Twist Front Dress for everybody and every body.”
The athlete explained that her inspiration for designing the dress was for women of every size to feel great.
“No one in the world looks exactly the same,” she explains in the video. “We are all different people.”
Despite being a disciplined athlete and seven-time Wimbledon champion, Williams previously admitted that she often lacks confidence.
"There have been so many times in my career when my confidence has been low," Serena Williams told us from the set of her June cover shoot in Miami.
"I don’t go into every tournament having the most confidence... I think that's normal.
"How do I cope with it? I keep it to myself, I use positive affirmations and I try to believe in myself. Then I take things one stage at a time."
