This I can definitely somewhat relate to...
My school's skirts were made of wool and i'm highly allergic to wool so if my bare legs touched them it would get really uncomfortable and I would get rashes and stuff.
Anyway, what I did was I would wear bike shorts that were slightly longer than my skirt itself so that there was always a layer between my legs and the skirt.
And in the winter I would wear leggings or tights, although I know catholic schools have a strict uniform code so I'm not sure whether those would be allowed.
