... does what someone wears make them a different person?
No, what somebody wears does not make somebody a "different person" -- but it does show what somebody is (or is not).
Let me say it another way. Your attire and your grooming is the first statement that you make to a stranger -- before you even get to speak a word.
who wants to sweat and not be able to turn their neck for 3 hours?
That's a manifestation of clothes that don't fit properly -- not the style of clothing.
