sometimes people sew for others, people actually you don´t know (for selling) and you just can´t take the right measurements for a well fitting garment. When you´re using commercial patterns that are already tested, you are not supposed to have any problem with standard proportions, but maybe you´re enrolled in the adventure of drafting your own patterns. In this case, as me, I´ve realized there are few ( super important) measurements I just don´t know where to find p.i.
-shoulder to shoulder width…and go on and on
many available standard size charts are very succinct because is all about guidance, does it exist a FULL chart or procedure to obtain these numbers?
