Ahem
Bingpup garter belt buckles
Thank you for coming to my ted talk

And alssooo the lotus belt buckle is not only to symbolise immortality but reincarnation and the fact Sy doesnt know Sj's roots/backstory by having the bottom of the lotus covered in fog/clouds.

So! The crown I feel is a gift from Yqy when SQQ became a peak lord based off with a stick(thats two that clicks into one when tied up) a cranes wings.
The lower hair tie is based off of yqy's designs and i like to think he made it to get finer motor hand control bavk after /thattt/.
