That's an interesting thing to think about. Quite frankly, I haven't thought about it recently.

Nowadays it's perfectly OK for women to wear trousers or jeans, which probably makes us think that it's not much of an issue any more, leastways not here in Europe. (Of course, there are several countries where women wearing trousers or jeans are frowned upon or they are simply not allowed to wear such articles. But I don't think I need to elaborate on this - it has already been discussed
ad nauseam I reckon.) However, believe it or not, there still are people who assume that wearing trousers or jeans is incompatible with feminity. As far as I remember, someone posted here once that her boyfriend was appalled by the very idea of women (including his girlfriend) wearing trousers.
As for me...I do wear trousers and jeans quite often. When I was younger, I used to hate jeans with a vengeance. Everybody was wearing them all the time, except for me. But now, at the grand old age of 25

I do. Well, not all the time but regularly, even though they still aren't my favourite articles. I even wear them with a leather jacket or a blazer, which is not the most feminine combo conceivable, but there you go...I'm not your typical girly girl, either.

I mean I do look feminine, but I'm a bit of a ladette on the inside...or might I say tomboy(ish)? The word "ladette" has rather negative implications, doesn't it?

But it's neither here nor there.
So anyway, I wear jeans and trousers but funnily enough I find dresses and skirts an awful lot more comfortable. Simply because they don't stick onto certain (very precious) parts of my body.

As far as femininity is concerned, you can look absolutely fit in dressy trousers or jeans but skirts and dresses give you a feminine look in a more traditional way. But I reckon my preferences have nothing to do with the issue of femininity, tradition or religion - it's just how I feel comfortable.
Well I hope that helps.
