Sparkly, I’m still not sure what you are saying exactly. In any case, my point was that one should not assume that something is okay just because guys don’t like it. If that’s not what you said, then I’m sorry for misunderstanding you.
I copied and pasted your words below. It very much sounds like you are saying that since guys don’t like headbands, they are tznius. If that is not what you meant, gread.
“i dont even know if guys think girls are cute in headbands so headbands are VERY MUCH tznius i think guys might not even like headbands which makes them even more tznius”
