This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
袛 combines the clothing radical 衤 with the phonetic component 氐. The exact historical meaning is uncertain, and it is rarely used in modern Japanese.
With 衤 (clothing) and 氐 (a phonetic component), 袛 might suggest a type of garment, but its meaning is unclear. Picture an ancient robe whose name has been forgotten.
For テイ, imagine a tailor named Tay making a mysterious robe: Tay -> テイ, and the robe is the unknown garment 袛.
