風雲改二(水着)
The [[bikini]] [[official alternate costume]] of [i][[Kantai Collection]][/i]'s [[Kazagumo Kai Ni (kancolle)|]], as seen in post #4026088. 

It differs from her original base/kai swimsuit in that her [[rigging]] is now smaller and instead of blue, she now wears a [[white bikini]] to go with the [[polka dot sarong]].
