OK, this probably isn't what you want to hear, but... I do think that there is something to the "I hate the way this material feels" thing, for some people. I've read about it -- forget what it's called, exactly -- but it's like a sensory overload disorder thing. When I was a kid, I used to refuse to wear velour or corduroy. I HATED the way they felt. It was like nails on a chalkboard to me. My mom thought I was insane. I also used to tell her that I was (and I quote) "allergic to squeaks" whenever we traveled in our van across country with a styrofoam cooler in the back (when we'd hit bumps in the road, the styrofoam made that god-awful squeaking noise it makes... and I thought I would go insane!).
Fast-forward to today... I now have a son (my oldest, almost 4-yrs-old) who is kinda weird about things like this, too. He hates the feel of his socks being "out of alignment" on his feet (and frankly, I do too... so maybe it's inherited! LOL).
I have no advice for you, other than to tell you that my mom and I used to battle over clothing, too, when I was a kid... she wanted me to wear dresses, and I hated dresses... and so she told he I only had to do it 2 days a week. Each day when I woke up, she let me choose -- dress or no dress today? I always chose "no dress". Mon, Tues, Wed... come Thursday, well, there was a lot of whining on Thursdays, when I had backed myself into a corner for Thurs and Fri outfit choices...

haha
It'll pass. I am a relatively normal adult now. I hate dresses, but I am awesome. Your daughter will be, too.
