On Instagram Sunday afternoon, Williams showed everyone that she was wearing sneakers under her formal dress that she wore to the Royal wedding reception for Britain's Prince Harry, Duke of Sussex and US actress Meghan Markle.

Little known fact: I often wear sneakers under my evening gown. These @maisonvalentino @pppiccioli gave to me last min. I told him be careful I tend to be comfy for long nights #beingserena
