No, this hypothetical wrestler didn't circumvent the rules. The rules state (almost everywhere) that the wrestler must make weight in _A_ singlet, not THE singlet he/she will wrestle in. In some cases, you see references to a "competition singlet" (whatever THAT is), but there is nothing that says a wrestler must make weight in the very same singlet he/she will wrestle in. In fact many kids wrestle in some of the sorts of singlets we see offered at many of the larger tournaments, rather than a "club singlet".
