I suspect some will not be down with the stripes of the suiting. But, I think it's still tasteful.
I always take a pass on this sort of fabric because even though it looks nice, I feel like it would require my brain to do somersaults in order to arrive at combinations I would be fully comfortable with. So basically I'm too chicken to select fabrics like this but I applaud you for being daring. As for this specific combo, there's nothing specific I can point to, it's just not completely harmonious. How's that for a useless critique
