What I found weird in Qatar (not away from the beach - women and men were wearing pretty much the same thing with the same amount of coverage away from the beach, unless thexwinan chose to cover her face and or hands, which was not the majority) .... Was that women were in the beach - not even wearing a burkini - but wearing an abaya, head scarf etc. .... While the man with them was wearing shorts and a short sleeve polo shirt.
I have to say I did think wtf.
So "modest" dressing is required for women at all times in public, but not men.
If the men had also worn their usual thobe and headscarf on the beach (with the accompanying level of inconvenience for a beach) - absolutely fine with me. But they didn't.
To make it even more wtf, when I was in west Africa a Dutch guy told me he was told off for wearing shorts in Ivory Coast - due to them not being modest. So clearly strict interpretation means no showing off your (even lower) legs for men in shorts. Yet this was fine for many of the men on the beach in Qatar, while their wives were stuck in an abaya , only able to paddle a bit holding the hem up.
If you want to dress modestly - make it males and females; only way it's equal.
Though tbh, with polygyny/multiple wives to one man built into the religion (though I understand it's not that common depending on the country); how is it ever equal anyway. I know theoretically the wife/wives don't have to stay if he does that (?) but ateotd it's not easy to leave for a no of reasons.
