What an interesting thread!
When I hear "womanly", I think voluptuous and feminine, in the style of Sophia Loren and Gina Lollobrigida. And not just curvy in terms of shape. It brings to mind that whole ethos that I would think of as Italian style (as opposed to French or North American, say). A relaxed sensuality, a mature beauty; maybe what "romantic" or some kinds of "dramatic" refer to as style descriptors. When I was growing up, that was the feminine ideal (which didn't match IT me).
I think this has become a less common ideal as youth and skinniness has trumped all (now that I no longer possess them...). But it isn't frumpy or matronly.
Maybe a bit of a hijack but: in the early 90s (I think) in Rome, DH and I noticed a female traffic policewoman. She was wearing a brass-buttoned, navy blue uniform--that was a fitted jacket showing off her hourglass curves, and a skirt. It struck us as so different to the Canadian policewoman's garb, which is pants and a boxy jacket from the same tailor as the men's uniform.
This whole thing led to some rumination (generalizations of course) on differing attitudes to gender differences in Europe vs North America (this is the rant, and based on when my kids were younger so maybe things have changed). The European attitude seemed then to be more "vive la difference" with an idea that we need women's contribution to the workforce, therefore we must have good mat leave, workplace childcare etc to level the playing field. Vs the North American view (better now I hope?) that if a woman wants to compete in a man's world, she had better make sure her pregnancy or child-care related needs don't get in the way of doing her job... Rant over, and feel free to disregard as I clearly don't know what I'm talking about...
