Oh, density and distribution is so hard. That's why I don't think any pattern generator programs will actually work, they try to take too many shortcuts. My low-waisted wardrobe is here with you. But I'm fairly consistent with the pattern companies I use, so I get a feel for their foibles. Beginning to see that I need my 'natural' waist measurement for most patterns, even if the fashion waist is much lower. Work comes to work I can just chop off six inches and draft a new waistband. (I'd love a me-shaped dress form, but there's barely room for me in here, let alone two of me.)
