Talk to him about how it is affecting you, like maybe how you feel like you have no freedom(?) - it may help him realise his own actions and its effects on you.
Ask him if he really thinks his own opinions matter more than yours, when really you both should be equal. Why should his opinions matter more?
Tell him that it is your body and so him deciding what you can/cannot wear is unacceptable - why should he attempt to have control over something that is not actually his?
Does he not think about your view of things? Tell him that he is being inconsiderate about how you feel and that him deciding what you wear will only bring relief/happiness for one side of the relationship (him), whilst the other half remains hollow and unsatisfied (you) - is that what he wants? Is this selfishness?.
It's all about making him aware of what he's doing and reflect on his actions, whether he agrees with what you say or not. Even if this still leads to an argument, he will probably end up thinking about all these things anyway.
