Designs displayed at Good Smile Cafe Exhibit
Don't ask me how they plan on doing a beach episode in a sci-fi anime set on a Waterworld. Still, there are swimsuit designs for the female cast members of Gargantia on the Verdurous Planet. The series' blog specifically calls attention to the illustrations when promoting an exhibit at Akihabara's Good Smile Cafe, running through this week.
By the way, if you're wondering about the ages of the female cast members
Yeah, that's official...
