Gender roles exist in nature but are vastly different among different species. In a lot of species the male is more fabulous than female.

Alternatively gender roles exist mostly for survival.
Men hunt or protect usually because they are bigger.

As survival based of strength becomes less of a concern gender roles begin to change.
Notibly lionesses who don’t need a man to protect them from most predators become hunters.

Same for humans as we enter into a more intellectual phase in human history “big man strong” isn’t as valuable as a person who knows how to use their brains well.
So it’s no surprise that gender roles are breaking down because they are no longer Necessary.

Now as humans you can chose to maintain old gender roles if they work for you or abandon them completely. Both options are for the individual to chose and neither is right or wrong.

So! You can chose to wear the outfit that speaks to your gender or you can chose not to care about that at all and wear whatever you feel like.

Both options are present both options are valid
