I encountered this word while watching a video on colors and people personalities in COMD1101.
I now understand that Solemn means someone who is formal and dignified. They are proper and educated. They like to to be classy.

I think the evening-wear example doesn’t quite fit with the word solemn, which is perhaps too serious to relate to getting dressed up. How was it used in the video? That’s an important part of the glossary entry, and can help provide you and readers of our glossary a better way to understand the word once you have a definition.
