We need to go back to the original xs-xl size range. Normal small, medium and  large. Then xs which is a shorter small, like a petite small length wise and the xl which is a longer fitting large for taller people. The "x" portion once dictated length iirc.  I am currently learning to make patterns and design my own stuff to make since I can't find what I want in human sizes. There must be a lot of other ladies out there doing the same thing. I am even having trouble finding smaller sized patterns online and in stores. Luckily it is very easy, most of the time, to resize a pattern down a few sizes.
