If Joe wants to wear red pants he can. The rights to unique clothing aren’t in the Constitution, but we still have them. Which amendment does this scenario refer to?

The amendment that this scenario refers to is the Ninth Amendment.

Explanation:

The Ninth Amendment to the Constitution, approved in 1789 in conjunction with the rest of the Bill of Rights, guarantees American citizens the protection of rights not listed in the Constitution or the Bill of Rights, establishing that the rights enunciated in the constitutional text they do not imply a denial of other rights retained by citizens. Thus, provided that any action or omission on the part of individuals does not harm the rights of third parties, it will be the right of citizens to exercise them.
