2.5m it is
I have actually gotten a solid grey suit cut out of 3 yards, not meters. I have also gotten a sportcoat with a large window pane pattern cut out of 66" of a Loro Piana fabric that was left over. I dont think there would have been enough to do patch pockets though!
I'm about a 41 chest, 5'11" and reasonably fit. OBVIOUSLY, these are rare cases and I would usually order 2 METERS for a jacket and 3 or 3.25 meters for a suit. My tailor is happy with those lengths for me, but this is a very big YMMV situation.
That would be just fine with me. If memory serves, 60 meters are required. Maybe we could set up a thread for it? Might be easier to track commitments, and would enable us to get a more detailed accounting of specs, and all the other fun details.
