Thank you! I think it really needs some adjustments as SD13 is at least lower than SG male which is 65 cm high. Please see SG measurements here: [link]
I have one question. I don't know the terminology, but is that single bold black line on the 'back' pattern showing where the band should lie on the dolls' hips?
I think the best way to understand this line is to take a pair of classical jeans and to examine their construction (see here: [link]). The top part is cut as a separate piece, and you may draw that line in any place you want: higher, lower, etc. You may even don't cut it but make a decorative stitching double line there. Hope it helps.
do you have some basic instructions for this? Do I cut four pieces yes? I would love a full tutorial if you could find the time. I could do a trade for it if needed.
(Does that make any sense?)
