Not that it's a concern, but the wider lapels are even in concert with most contemporary fashion. The Brits and Americans, and those who wish to imitate them, are mainly the last holdouts of the skinny lapel, with the rest of world either never adopting it, or having moved on many moons ago. Perhaps this British clothier is testing the waters.I just love hounds tooth, and think this is a particularly good rendition of it. The wide lapels are another aspect that set it apart from the ordinary. Not everyone’s cup of tea, but I keep checking their site to see if they bring out another sports coat or suit with a similar lapel. It makes the sports coat stand out from the crowd, IMO in a good way. I am fortunate that even though it is memorable, my rotation is such that no jacket gets more than a few wearing per season.
What is significant is that I think it's especially flattering for you, very dapper. Perhaps even a bit DoW'ish!
It certainly looks like a Donegal style tweed to me, and a rather nice one!
