1e9a                        Hawaiian shirts are originally made from Kimono or likely yukata material. You are right that print isn't any where near kimono material -- I keep trying to figure out why she choose that. The trim you are correct about too but anime ... Does take liberty with mixing ainu designs with Yamamoto Japanese ones. She also seems to be mixing a kimono design with a yukata ... I've no clue what she was looking at for a design basis ... Maybe some image off eBay? Her biggest mistake is that the sleeves are completely wrong.
