This item was from the Aぇ! group Debut Tour ～世界で1番AぇLIVE～. I didn't wear it during that tour, but I did wear it over my clothes only during the Kamigata Boys live performance in the late afternoon of late September. Also, I'm not the type to sweat much, haha. I have washed it since then. There is no lingering scent that might be bothersome, such as from fabric softener. Please understand that this is a used item. Furthermore, it will be folded by hand for shipping, so I would appreciate it if you could overlook any new wrinkles that may occur during that process.
