"When a person is in fashion, all they do is right"

This quote by Lord Chesterfield is a commentary on the power of appeal and the influence it can have on people's opinions. It suggests that when somebody remains in style, or popular, they are seen as infallible and whatever they do is seen as right. This might be interpreted as a criticism of the power of popularity and the tendency of individuals to blindly follow those who remain in fashion. It might also be seen as an alerting to those who remain in fashion, as it indicates that they should be careful not to abuse their power and influence. Ultimately, this quote is a reminder that popularity is not a trusted step of a person's character or worth, and that it ought to not be utilized as a basis for making choices.
