Merino Clothing (base layers, etc)

Why is it that very few companies do a proper small size? Most companies seem to start at 36" chest, but i'm 33" and 6ft. I can't believe that i'm in such a small minority but it seems impossible to get things that fit right (as base-layers) but aren't too short.
