So I see that Kyle was in fact busy measuring the Schneider goods.
For the Roman sweater, what I see and read says that it is wider than it is long (i.e., cropped but broad across the chest):
From what Greg said earlier, my guess as that as a size 40 (and a medium in Inis Meain) I'd wear a 5 in this sweater. And that five has an almost 50 inch chest?
I just need to trust M. Schneider on this one, right?
