There is a scoliosis forum. It might be a good place to start.
I have very slight scoliosis - not enough for a brace or anything. My sister's bestie had severe scoliosis and wore a brace until her late teens and now you wouldn't notice if you looked at her.
I'll find the forum (I have it in my bookmarks) and add it in a minute. Actually I'll PM it to you. I'm not sure if it's against the guidelines or not
