What about a woolen flannel? I don't know, I am still quite enamored with the idea, although I'm probably going to get it as a blazer suit combo. I like brown tweeds but I want something softer and less scratchy looking/feeling.
I'd be interested in a rerun of either of the brown frescos in any case.
The difference between worsted and woolen is pretty small in this case. If a plain brown, worsted flannel SC is going to look bad, going woolen isn't going to radically change it.
There are fuzzier hopsacks out there, if you want that sort of texture. Something with a cashmere blend and chunkier weave will prob be a little fuzzier.
There are also softer tweeds out there. Fox's tweeds aren't particularly prickly.
