Do you think it's not right how a Muslim female must cover herself up and not expose any of her body?

As a non-Muslim female I get to pick and choose what I like to wear without any man telling me I cannot wear it. How can females say they are liberated when they're hiding behind a veil or burka. I've seen Muslim females completely hiding behind a burka where you can't even see her eyes. How can she say she's liberated? I don't understand.
