Thematic and clothing similarity, that's all. Some would even go as far as to say that Kiso copied from Murasa's style, but really, sailor uniforms are very common in Japanese media.
AkaneYakumo said: One of the Kancolle artists, ugume, is a Touhou artist. (Yes, he's responsible for Kiso's design)
He even drew Murasa with an eye patch long before he designed Kiso. He probably saw the sisters ship wearing a similar sailor uniform, so he just went with it and put Murasa's design into Kiso. Or he did plan to base it from Murasa from the beginning.
So Kiso copied from Murasa? With how it is then I'd say yeah, but let's just put it nicely and call it "inspired". Besides, it was done affectionately.

Legit enough to add that image in "Origin" pool or not?
