SamTheGreek said: What did you mean for it to say? I can give you a correct translation if you like.
You'd have to ask the artist that, most of whom don't browse Danbooru. I'd assume they meant something like "showing knowledge of fashion in the library."
Yes, that is me. And thank you. I'm totally gonna show this to my students tomorrow. Minus the "balls" lines, of course.
Literally "Greatest knowledge I bring from books"
The greatest knowledge comes from books.
Optima scientia advehitur ex libris.
Suggestion from SamTheGreek.
