I personally find most dress codes annoying, especially if they are predicated under religious or moralistic precepts. We live in a tropical country, hot all year around and in many public offices we are not allowed to wear summer clothes (and I am not talking about swimsuits). In some public offices men are not allowed to wear bermuda shorts, but women are allowed to wear miniskirts. In others, women are not allowed to enter if they are wearing anything withouts sleeves (short or long), so forget about tanktops or blouses without sleeves.

The alleged inmorality brandished against these clothes is irritating when the places that forbid them are the craddle of inmoral/dishonest/corrupt/mediocre behavior (courthouses, military facilities, churches, schools, etc.)

In any case, asuming there is something possitive behind these regulations, I think that when it comes to religious justifications not to wear certain kinds of clothes, like bikinis, people should just make their choices: you either honor your religion and all its prohibitions and forget about the corrupting world that runs counter it, or decide that your god is loving enough as to ignore certain lapses (for survival's sake).
But people want both things and "my-house-my-rules" applies to both Christians and Muslims so, it's a lose-lose situation. No one makes concessions but all want to win.
It's a very frustrating children's game, only people even die for playing it.
