Who and What Is the Modern Girl
A Clear-Thinking Person with the Courage To Be Different and the Cleverness to Avoid Extremes
By Carol Cameron, Director, Department of Beauty Hygiene
THE history of the world proves that every age has had its modern young woman who has “given the current commentators and moralists sufficient reason to lift their eyebrows. As far back as the days of Ancient Greece, Aristotle, the philosopher who thought little of women in general though he chose to marry a second time, had quite a bit to say about the bold young daughters of Athens. Yesterday we were aroused by the scant dress and impertinent manners of the “flapper,” a type which has long since grown up and settled down into that complacent and highly respectable status known as the young matron. The flapper of today is in the minority. Pertness is no longer cute nor is it regarded as especially complimentary to be slapped on one’s back and labeled a “good egg.”
The modern young woman has realized for some time that clothes which bring out one’s latent glamor, as well as drawing discreet attention to one’s most attractive points, have much more possibility of allure than a too generous revelation of exposed surfaces, particularly so when those same exposed surfaces are in the process of recovery from the various disfigurations of insect bites and sunburn. She has also come to the conclusion that being charming to other people, in other words courteous to those older than she, more considerate of one’s own family, and a little more graciously aloof from the fresh boy next door, has certain advantages also.
Today’s young woman is a rather clear-thinking young person who has not only the courage to be individual but the cleverness not to run to extremes.
