fine clothes
襛 centers on fine, elegant clothing. The meaning is narrow and concrete, referring to garments of high quality or elaborate dress.
襛 combines the clothing radical 衤 with 農, which likely provides the sound. The character is rare and its exact historical development is uncertain.
The left side 衤 is clothing, and the right side 農 suggests something rich or abundant (as in agriculture). Picture a farmer's finest festival clothes: 襛 means fine clothes.
For ジョウ, imagine a tailor named Joe who makes fine clothes: Joe -> ジョウ, and his elegant garments are 襛.
