From what I can gather, for you Freedom= Having choices. Well going by your standards even the girls who are forced to cover up have freedom in that they can choose whatever to cover up with e.g. choices between different types, colors, designs of abaya, niqab etc etc. But you'll go that this isn't freedom. The whole enforcing to cover up dictates that this isn't freedom.
So I ask you ... What is 'enforcement'. From what is generally believed, it is 'the act of compelling compliance with a law rule or obligation'. Well.... how do you do that? The answer being ... Negative consequences. So for example in the whole forcing to cover up case the consequences are usually dished out by what liberals like to refer to as ' moral police' which usually go ... 'You don't cover up and xyz will happen' .... which usually involves consequences of some kind, maybe verbal and in extreme cases physical. So there is this fear of consequence which results in compliance hence the act can be termed as 'enforced'.
Coming to the fashion industry, you are fed the idea of what is 'cool' 'hot' 'in this season' etc. and not having it on has negative consequences. Be it bullying at a young age, be it being laughed at, being a social outcast etc etc. In other words, even the industry which you consider free because it has 'some choice' presents certain consequences when you say no to any of the choices being presented and the effects of this industry stretch quite a far, for even in the whole 'cover up' clothes there is the fashion industry telling you ... this certain design of 'cover up clothing' is in this season and the other one is 'so last season'. So like I said, If women should have a problem with someone ... for 'dictating how you dress' ... your single biggest problem should be with the very fashion icons that you idealize ...
