Also known as: 三隈(2016水着)
The original Bikini Official Alternate Costume of Kantai Collection's Mikuma (Kancolle).
It consists of a plain Red Bikini and matching red Flippers, with a Bodyboard carrying her real-life seaplane deck pattern and her nickname "Kumarinko" printed on it. The outfit gained notoriety for its Bad Anatomy and was never repeated, instead opting to go for a new swimsuit design that's been used since 2017.
