Also, passing would work for height. Suppose you're 5'11 but your friends are around 6'1 and you were close friends in kindergarten (when you were all shorter of course). You begin wearing platforms that add about an inch to your height. You hang out with other tallers and so people just assume that's what you are, they likely don't insist on measuring you in bare feet at every opportunity. Laws affecting this social construction of "tallers" have much less impact on you than might seem to be the case looking at a medical chart. You would be said to "pass" for a taller.

Passing was (and to a lesser extent remains) crucial in the US and many places where variations in appearance were crucial to racial assumptions. If you look white and you act white then, most of the time to a first approximation you are white. But of course this opportunity is much more open to a relatively pale-skinned person than to a dark-skinned poor person which is a further problem on top of the problem that now people are lying about who they are.
