American Girl "Rebecca" Inspired girl's pajamas

[Faliciagayle]

My daughter would love to have pajamas to match her doll, but I have no interest in having her sleep in flame retardant polyester.  http://store.americangirl.com/agshop/html/item/id/137387/uid/631

any ideas for a similar style from a pattern company?  The pants I can figure out myself, but it would be nice to follow a pattern for the top....
