It can be rather awkward if you appear at an event wearing casual clothes while everyone is wearing formal attire and vice versa. Nonetheless, playwright and actor Noël Coward didn’t falter when a similar event happened to him. In 1918, Coward was invited to a gathering organized by Tomorrow Club, which was composed of literary bigwigs at the time.
Coward went to the meeting without knowing the dress code. He arrived there looking like he was going to a job interview, only to find that everybody was wearing casual clothes. Everyone’s attention was on him as he walked inside the venue. He then paused for a moment in the doorway and said, “Now, I don’t want anybody to feel embarrassed.”
