What restrictions, what liberty? This is a bit of a no-brainer, Phil. Apart from people who work in back rooms or at home, most jobs require some form of uniformity of dress. Maybe you've never had a job, so you don't know this. If you think you're going to get a job as, say, an estate agent, kitted out in a velour tracksuit and a pair of Reeboks, you're much mistaken.
I'd suggest that the notion of liberty be taken a little more seriously, like why people are murdered daily because of the illiberality of the regimes under which they suffer. Dress codes as an infringement of human liberty? Yes, if they're placed by force or threat upon a person, for example, the Taleban's imposition of full veiling and cover upon Afghan women, upon pain of imprisonment after a nice public whipping. No, if it's just a matter that to be a brain surgeon, you need to cover up and protect your patient from your filthy germs.
