Sailor Coats?

I'm on the hunt for a sailor coat (sometimes referred to as a Japanese schoolgirl coat), and sadly I'm not having much luck. I've seen so many in the past released by Sechuna, Topshop, etc, but they all seem to be sold out now. I'm wondering if anyone here knows of any Taobao or Rakuten shops that may still have some available, or perhaps any other misc online stores? I did find some on eBay UK, but only one is my size and the bidding is pretty fierce. So I thought I'd ask here!
