Would the world be a better place if everyone has to wear a burqa, or had to be naked Watch
however, if it had to be one or the other at all times, it would be more practical to expect those in cold countries to be burqa'd, and those in hot countries to be naked for obvious reasons
on the other hand if everyone had to wear a burka then the makeup and hair industries would plummet but then less time would be spent on perfecting your appearance and personality would become more important. Providing you had to wear it 24/7 it would make washing your hair more difficult
Well it could be an idea, but imagine the embarrassment if you turned up to a party where everyone was in a burqa, and you were the only person that turned up naked.
