This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
帾 combines 巾 (cloth) with 者, which likely contributes the sound. The exact historical development is uncertain.
The left side is 巾 (cloth), and the right side is 者 (person). Picture a cloth banner or flag with a person's mark on it, but remember its meaning is unclear.
For ト, imagine a toe (ト) wrapped in a cloth (巾) with a mark (者) on it: toe -> ト.
