At least for part of your question; I recently ordered a suit from a danish"tailor (who gets their suits sewn in Portugal). The measurement process consisted of doing a 3D body scan, with minor manual measurements (such as deciding fit). You can then use your existing scan, to order new garments. But preferably, I would still like to consult the tailor in store, since there's more to fit than getting the size and length right.
