What does ‘demure’ mean in the latest social media trend?

The latest internet craze, "very demure, very mindful," has recently gone viral on TikTok. 
 

This trend was launched earlier this month by beauty influencer Jools Lebron. 
 

It has quickly gained popularity, with numerous celebrities such as Jenna Ortega, Jennifer Lopez, Lindsay Lohan and many more joining the trend.
 

Demure means reserved, modest, or shy, often used to describe someone who is quietly elegant or not ostentatious.
 

Her demure smile and soft-spoken manner made her a favourite among her colleagues, who admired her understated elegance.
 

Despite her demure appearance at the party, she confidently took the stage and delivered an inspiring speech that captivated everyone.
