I'm going to read the book first but i have troubles with finding the dutch translation also the girl in that picture looks like she is wearing no pants and just has her butt painted blue.
The dutch translation in 2nd hand can be found in probably any bookstore. Bol has them for €10, my guess is you can find them even cheaper at bookstores. Personally I would prefer the english version but you should definitely give it a go, it's to this day one of the best sci-fi's out there.
You'll read the book and find out those are 'skinsuits'.
You probably should read it in english. And you can find it in ebook everywhere for free.
