I was initially planning to wear something more casual than navy mohair to the symphony the other night. But the after six starting time called for a white shirt and black shoes, and I thought a bow tie would be appropriate. That led to the suit, and there we have the slippery slope that ended with trousers worn too long.
The need to adjust one's braces to accommodate different trouser lengths is one of the challenges of using different tailors, each with his own pattern. The only reliable solution is to dedicate a pair to each suit, but then a man is stuck with a color that may or may not be in conflict with the rest of his clothes.
And so it goes.
