Amazon CEO and the world’s richest man Jeff Bezos attended the company’s board meeting in pyjamas – dark blue nightsuit with white piping.  He later put up an Instagram post explaining that he did it for a cause.
PJammin events are hosted in ‘solidarity for the thousands of children living in their pyjamas for months while receiving medical treatment.’ Each event helps raise money to support American Childhood Cancer organisation.
Employees at Amazon followed Jeff Bezos example and also started ‘PJammin’ on Instagram.
