最上改二(水着)
The [[bikini]] [[official alternate costume]] of [i][[Kantai Collection]][/i]'s [[Mogami Kai Ni (kancolle)|]], as seen in post #5505650. 

She retains the same [[white jacket]] and grey [[sandals]] of the base/kai version but now wears a [[green bikini]] top and [[green shorts]]. She also has a kouhyouteki midget submarine sticking out the jacket's right pocket.
