Completely besides your point, but Iran mandates a hijab (head scarf, no veil). Burkas (often blue, net in front of face) are mainly found (not sure if mandated or expected) in Afghanistan, whereas the Saudis use niqabs (the black veils). The hijab mandate being the least repulsive.
I know it's an odd nitpick, consider it a compulsion of mine.
To be fair, there's no logical problem with an example of Iran demanding UK women to wear burkas even if burkas aren't their cultural norm.
