"Another nice colour combination. I've been meaning to ask: sometimes your left collar is curled over, with the right one laying flat. If you wore button-downs I'd assume one side was buttoned and the other not, but they seem to be regular spread collars (unless they're of the hidden button-down kind?) and it seems too frequent to simply be random movement of a very soft/unlined collar. Is it a deliberate thing or just random?"
Sharp observation. Hadn't noticed myself before, but I think it is because I tie my four-in-hand with the narrow end of the blade on my right side: I think the correct procedure is the other way round, but that´s how I learned to do it from my father. It might mess up the collar roll when you tighten the knot. Only explanation I can think of..
Thanks. I don't think it looks bad, by the way; it comes across as a natural/normal variation. I was just curious as to its evolution.
