Since multiple people asked me, here is how i made my xayah feather cape : (Swipe to see) I got 4m of cheap purple fabric and wire (use electrical cord if you want em to be more flexible) and a big can of super glue !
I took a big brush and applied glue very thin on both sides of the fabric and glued them together with the wire in it. The gradient on the tips were done with spray paint and the highlights with white acrylic paint. In the end i carefully glued the feathers on top of each other with hot glue and attached them around my neck with a band of leftover fabric !
Hope this helped c:
