This is not a problem. You're creating a problem where it doesn't exist.

If you want to dress up, dress up. Good for you. Glad you're pleased with that self image and are getting out of it whatever you're getting out of it.

As a feminist, however, you shohld be pushing back on the notion that one has to dress up in order to be correct with their womanhood and performance of femininity.

In other words, can you wish me well too? My typical go to is a ponytail, no makeup, blue jean shorts and a tshirt. Sometimes a cami and a poncho. Oh yeah, shades. It's Arizona, what can I tell you?

I don't own a dress. I don't do froo froo. Nothing against froo froo, I just don't like it, for me. But froo froo will always be available for those who do. I don't like it because it's constricting to wear, it messes with your gait, the fabrics don't breathe well in hot climates which causes issues, I lose too much time in maintenance of makeup and those clothes, lose a lot of ability to be spontaneous too, etc.

Can you be equally happy for me that I feel free, happy, myself, and sexy as hell in blue jeans and a poncho? Are you willing to stand by that the reality that both of our choices of dress and aesthetic haven't got a damned thing to do with our femininity? But what we inspire does? That kind of thing?

If so, then congratulations, you're getting (at least) that part of feminism right. You needn't worry. There is no problem here. Carry on.
