I did some Googling, and it seems that the Big Trad organizations (SSPX, CMRI) have each standardized on a given wording, that is used on all chapel websites.
I attempted to dig in my memory back to what we had posted in the Independent chapel where I grew up, founded by Thomas A. Nelson in the early 70's.
I wanted "old school" because it means an unbroken line with Tradition, and the Church before Vatican II. It's the most "pure", as it were. Nothing added, no obsessions that crept in later, etc.
Anyhow, here is what I came up with. The line about men was almost certainly absent: let's face it, when it comes to chapel dress code, men are never the problem. Men don't regularly expose their whole arms, show off their chest, or much of their legs. Unless you go full Novus Ordo "beach attire", which is common sense for virtually ALL Trad Catholics, men's dress is not a problem. Men just don't show off flesh like women are tempted to. Men and women are different. Perhaps that was captured in the "original" version of this Chapel Dress Code? It wasn't afraid to be politically incorrect by focusing on women.
Still, I wanted to give some mention of men's attire, since this IS 2022. I mentioned things that men MIGHT actually do. And instead of talking about specific clothes, I kept it concise: wear your Sunday best. In other words, there should be nothing BETTER in your closet than what you wear to Mass on Sunday. That is going to be different in India, Africa, Texas, Canada, the Midwest, or New England. Custom, including generational custom, DOES enter into it. What would you wear to a wedding, or to meet a high dignitary? Again, that varies by culture.
