The two third and fourth from the right look barely distinguishable in pattern - are they radically different in style or is it something only you and a discerning SF member could tell apart? I was wondering if having two POW suits was de trop but you've certainly answered that question!
The fabric is indeed pretty similar, It is the deco stripe -the windowpane overpaid- that is different. One is purple and the other blue. The farthest right garment is a sport coat. My view on duplication in the wardrobe is a little outside the norm. I have two white suits: one is double breasted and silk the other is linen and single breasted. That is different enough for me.
