Anybody can buy a black suit and sew some gold braid on it... the sensitive bits are the company emblems, which you should remove before disposing of a uniform. Without those, it's just a slightly decorated, poor quality black suit.
Every company I have ever worked for has been lax when it comes to uniforms... usually, when I have requested a list of what I have had to return, I have had 2-3 uniforms left over.
I know one guy who kept a uniform after he had left a company, and then wore it into the city to clubs, trying to pick up girls. Not sure if it worked though!
