Reply To: Orthodox hats for Shabbos — what do you wear?

And, if you want to tell me that Chazal knew everything

I don’t think anyone says that. I think when the gemara applies ??? ?’ ?????? to Chazal’s knowledge of the physical world, it means that Hashem reveals some (not all) hidden things to Chazal, so that it’s no wonder how they know certain facts not otherwise known.

It doesn’t mean that they necessarily knew the Far Eastern haberdashery styles.
