As I understand it they only wear pink if the buyer designs them that way. There’s not even a single image of a pink-wearing doll on the homepage of their web site.
I’m mildly surprised they don’t have any “boy” options though. Even if they would account for a small percentage of overall sales it seems like it would be an easy option to add since each one is printed on demand anyway.
EDIT: I was wrong, they do make boy dolls. They just didn’t show any on their home page.
