Since WoWS is now in closed beta and the NDA is lifted, the skins are located at:
(where your game is located) > res > content > gameplay > japan > ship > "shipclass" > textures > "blahblahblah_a.dds"
if any aspiring skinner wants to try anything.
Tried to put a school swimsuit on a destroyer but messed up the sides big time. Texture images are really hard to read in photoshop
