No, no, the construction is still perfectly intact. No loose or broken stitches--astoundingly.
The cloth is what died. Awful (beyond the realm of sprezzatura) fraying at the edges and points of the collars and cuffs. On all 20 or so shirts. I will never buy Riva shirting again. The mystique dies after you have to live with it.
That said, my Riva is 100% cotton. Maybe the blend is more durable? No idea.
