Plus size hiking clothing

Recently I ordered a XXL pair of hiking pants online, unfortunately , they are a 12 to 14 at most not 20 to 22 .
Its a frusting search to find hiking clothing in larger sizes
I get frustrated that many manufactures of specialised technical clothing finish at a womens size 16 .
Women who are a larger size, have legs that take them places too, over hill, dale and through the bush.
It leads me to wonder where to look for such clothing in " my perfect size " and also if its worth sewing my own
Is anyone out there in the real world sewing their own custom made hiking clothing ?
