Taken from the P Johnson Tailor site; an up-and-coming Australian MTM outfit (do a google).
And no, I don't work for them.
But I am getting something made by them!!!
Personally I think this thread beats the brown and navy one since grey really is the most verstile IMO... If this is too much of an overload just let me know... Part 1 is various grey shades, textures, and patterns in suits and sportscoats Part 2 is other uses of grey I found interesting.
