I hear you, but fashion is fickle and all that, and lately gingham shirts with suit and tie have become quite trendy. Whatever. It's not like I find it outright offensive, the way I do some fashion trends. I mean, neither is it something I love (for all that it can occasionally be done well), but admittedly I'm more of a traditionalist in such matters than I am a follower of fashion.
As for the "particularly at a wedding" part, it really depends on the type of wedding. At some, a gingham shirt with tie would be unacceptably dressy, at others it would be far too informal. The OP hasn't opted to give us any specific information about the nature of the upcoming wedding.
Assuming a relatively informal wedding - but one where at least some of the men will be wearing suits - I suppose a gingham shirt with silk knit tie could work. I mean, the knit tie is itself somewhat more informal than many other types of necktie, so at least one could maintain that it's a good match for a gingham shirt. Plus, I just happen to like silk knit ties.
