This happened to me as well when ordering DD1's big girl room stuff.. I also have other Stanley pieces in my home. It takes awhile, but well worth the wait!
DD has the Ma Marie in black and I adore it
We ordered ours in January and were told it would take 6-8 weeks. It came in only 3! I read an article online that said that, since Stanley moved all production to the US in November, they try to ship all orders in 4 weeks. Hopefully that will be the case for you.
We love our furniture by the way - it looks amazing!
