But the evidence you have is, there’s 2 people who you don’t know that are saying “the clothes exist and they have a property that if you cannot see them you are dumb and/or unfit”, and there’s 2 people who you really really trust that are saying “look at these fine fine clothes, they really do exist”.
Collect more evidence.
If possible, find a person who never heard about the supposed properties of the clothes, and ask them to describe them to you. If they can’t, maybe they are stupid, but then find another one and… uhm, if everyone who didn’t hear about the supposed properties of the clothes is stupid, that’s suspicious.
Unexpectedly invite a few painters, put them in different corners of the room, and ask them to paint you in the clothes.
Alternatively, test your ministers. First, meet them with the clothes; next, without them. If they see the clothes both times...
Put the clothes in a bag. Add a few empty bags. Ask your ministers which bag contains the clothes. If all of them failed, ask the tailors.
