She'll probably want an all purpose- it's less expensive then dressage saddles at any rate! :-) Dressage saddles sit you really deep, and (to me) are odd to ride in at first, and take some getting used to. But then again so do close contact because you sit kinda perched there more forward on the horse's back. You can really feel the difference between a close contact and an all purpose.
The saddle I looked at today is an All Purpose. I sat in several different styles, but the All Purpose is the one I liked.
