Today we have the Lemon House Uniform. This could be used to cosplay as Eiko, Shizuru, or Nagisa. The pants could be any shorts really, but the closest would be any black shorts. The shoes depends on your character you want to be, and there you go! We also have Squid Girl herself which you can find in the category section above.
Pants: Any shorts
Shoes: Either Ninja Sandals or Basketball Shoes
