Sorry to break it to you, but women don't fancy fashionable men. They fancy men who wear Hollister t-shirts, go to the gym alot and use too much hair gel, in other words, twats.
Now I've got that bitterness out of my system, I shall answer your question.
I can actually relate to your situation quite alot; my ex was really into hipster fashion and within a couple of months she had me in fair-isle jumpers, skinny jeans and quilted jackets. I even had the standard 10mm stretcher in my ear.
I really regret that period of my style now, I secretly wanted to dress as I do now (classic, heritage-influenced). I think girls, if they notice style at all, apreciate something minimalist, refined and masculine. Think James Dean, think leather jackets and plain white tees.
Now I personally don't dress like that. I just love tailoring too much and I sometimes think my rather more formal style might put off a certain group of women. But then again, I wouldn't want to be with said women. That's the point; dress for yourself, but also for the sort of girl that YOU would like to be with.
