Fundamentally, to me femininity means having a female body. I feel feminine when I'm naked. I feel feminine when I'm wearing an old pair of jeans, putting up a tile backsplash. I feel feminine when I'm all dressed up too.
What I choose to wear or not wear has no bearing on being connected to my womanhood or my femininity. Granted, wearing a pretty dress at a function, when my hair is just right and my makeup has taken 5 years off my age is good too, but that's just window dressing. It doesn't make me feel any more feminine than when I'm naked. When I was younger, I knew what to wear at clubs to get the guys to look at me and it made me feel good when they noticed, just like the guy who feels "Man, I'm a stud" when a girl falls all over him. So maybe he's wearing studly clothes that is causing this reaction in the girl, or maybe it's the fact that he has broad shoulders and slim hips and the clothes just accentuate that. But the fact remains that if he was naked in a room with her and she was still all over him, he'd still feel like a stud.
Because it implies that women who aren't all decked out the way CDers like to see women, somehow aren't as attractive? How many times have we seen in this forum, "I'm a lot more attractive or feminine than my wife".
