Oh, then I misunderstood you. Sorry about that.
However, I do consider you an authority.
I get a little confused with the term "repp." Are you referring to a tie whose fabric is ribbed, or are you including the diagonal stripes in the definition?
Then there are those who say you shouldn't wear wool ties in spring and summer. Cotton and linen ties in patterns above are tough to come by, at least in the places I've looked.
