Biblical femininity is not dresses, pink, tea parties or kitchen work. While biblical femininity influences our behaviors or appearance it in and of itself is not an action or a fashion statement. It is a character quality, part of our inner self. Some of godly femininity is in the innate differences between the genders. While other aspects of it are chosen character qualities.

Women are created to be nurturers, wanting to help others, tender/compassionate, givers of self. Which is why nurses, teachers and social workers tend to be women. We also crave stability, safety, and understanding. Woman's movements in history have focused on creating safety(temperance), building up culture(school for all), or fighting abuses(abolition). Yes men join in and fight too but woman have been the front runners, some of the most vocal writers, the heart and voices of these movements. 

Scripture lays out some very unpopular and difficult character qualities for godly wives. There are of course qualities that all believers should endeavor to have but wives are given specific ones.
