The suit and tie is hardly universal. In Hawaii, it the understated Aloha shirt which is used by a vast majority of white collar workers, along with dress pants and dress shoes. The ladies use muu-muus which are a lot more modest than the standard dress and just as feminine.
**Wow! I did not know that.
Growing up, I definitely remember that my dad’s go-to church outfit involved his “good” jeans (the work jeans were spectacular ripped and patched due to the demands of work in the woods) and his cowboy boots (his work shoes were either rubber boots for sloshing around in manure for the the farm or logging boots for the woods). If you knew him, there was an obvious distinction. The Protestant pastor wore a suit (and maybe a few older men that ushered) but as a kid, I always felt it that was a bit weird, because in our world, suits were almost only worn for weddings or funerals or graduations.
I’ve also heard that a lot of Mexican men wear cowboy boots and cowboy hats for formal occasions. I haven’t been able to find a good cite for that (although that reflects what I’ve seen after church many times in Texas), but I just stumbled upon this:

Apparently, there’s a white Latin American shirt called the guayabera that is regarded as being a full equivalent to standard Western business atire (suit and tie). There’s a photo at the link showing President Obama in a suit surrounded by a sea of Latin American leaders in guayaberas (and untucked, too!).
The key is to make the effort to dress your best at mass at the same time keep in mind that the standards of appropriate dress is dictated by culture we live in.
