I'm an expert at ebay sells. I happen to be a powerseller and I also have about 5 years working with paypal very closely. Its my business and my life.
Find the receipt that arrived to your email, if it says anywhere that your purchase is covered by "buyer protection" then you are all set. You will get your money back in maybe 20 days maximum. It doesnt matter if he removed his bank account, paypal will cover you and then send his account to a collection agency. Bad news for him.
If you don't see the buyer protection or says "buyer protection program not available for this purchase" then you can always call your bank and file a dispute as well, saying that you received a broken item and paypal or usps wont cover you. The bank won't play this game, they will go ahead and refund your money immediately. I guarantee you will get you money back one way or another.
I'm sad to know this happened to you and your gf. Making an effort to dress your baby right and some a%#hole does this thing.
Merry Christmas for you and everyone in your family
