What you need to be aware of is that in Christian circles a lot of old debunked male/female stereotypes are still spoken of as if they were true.
Take the concepts of masculine and feminine, most people know they are social constructs and change through time and from place to place, but in Christian circles an idealised 1950's media portrayal of masculine and feminine is held up as the gold standard, as God's will even.
The late 1940s and the 1950s were a peculiar period in North American history. One interesting effect, perhaps not as trivial as it superficially appears, was as follows (I had to research all this for recreator's costumes for a local museum, dedicated to the forties/early fifties).
During the war years of the 1940s, women's clothing changed dramatically for two major war related reasons. A shortage of fabric, because most was alloted to the war effort, resulted in actual ordinances detailing how much fabric could be used in a piece of clothing, resulting in dresses and skirts being made narrow and quite short. A 1940s house dress typically came to mid-knee, with a narrow skirt prone to riding up when a woman sat or bent. The other phenomenon was the womens' war effort, working in factories, in industrial jobs, and in active nursing/health/aid kinds of volunteer positions. All of these required the women to wear coveralls or trousers for comfort, ease of movement, and safety. Pattern books were full of designs to fulfil these particular requirements, and there was also a huge upsurge in the number of women who owned sewing machines and made their own clothing from these patterns.
Come the fifties, with plentiful fabric and a lot of fashion designers and manufacturers eager to expand their war-reduced market, plus the return of soldiers pushing women out of the jobs they had taken on in the absence of men to fill them, and women's clothing took a complete turn. Hemlines dropped considerably, skirts became impossibly full, utilizing yards of fabric and fussy decoration, and patterns became more complex, more difficult for a woman to sew at home. 'Slacks' became a strictly casual wear choice, no longer identifying a woman as a person working outside the home at an important job. 1950s typical, ordinary, women's clothing reflected high fashion to the extent of reducing women's ease of movement - you always had to be careful, wearing big, full skirts, to stay out of windy situations and to avoid your clothing getting caught in things, completely useless for most jobs outside of an office.
So it is interesting that particular subsets of Christians (and really, subsets of men in general) have come to think of the feminine image of the 1950s as an ideal, representing as it does a post-war return of women to a kind of confinement in the home, and symbolized by restrictive, extravagantly wasteful (in terms of fabric usage) clothing. You could say fashion designers bear some responsibility for creating that image.
