This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
襳 combines 衤 (clothing) with 韱, which likely contributes sound. The exact historical development is uncertain.
The left side 衤 suggests clothing, and the right side 韱 is a complex shape. Without a clear meaning, picture a mysterious garment with intricate patterns.
For セン, imagine a centipede crawling over the intricate garment: cent -> セン, and the many legs match the complex right side.
