I already had this in queue, but thank you to Vicky for submitting it as well! Here is Kyary in Candy Stripper’s “BONE HANDS BORDER ONE-PIECE” in emerald green x black. Available here on their online store for 14,490 yen (approximately $181 USD).
Please note: Candy Stripper does not ship internationally. To purchase this on an online Japanese store, auction site, etc., you must have a friend ship it to you or purchase the item through a shipping service.
