I have two G+R shirting fabrics (oxfords). One of them is a bit shiny and wrinkles extremely easily. The other is OK but needs many more wash/wear cycles before it will hit the sweet spot and look really good (it currently is a bit too 'fine' for an OCBD. Frankly I strongly prefer my 'no-brand' sky blue oxfords and 'no-brand' university stripe oxfords to the G+R oxfords (even if they were the same price).
I have two jackets made from Dugdale worsteds. They get shiny pretty easily and require extra brushing to keep them looking good. The Dugdale flannels I have are nice but show wear in the crotch quickly (from rubbing I guess). The green cords I have are beautiful and soft. Too early to comment on durability. YMMV.
Are the green cords brisbane moss?
