APB on Ones That Got Away

This is #1 on my list of items I look for on ebay on a daily basis and sadly it always comes up in xsmall. I'm dying to find this in a Medium but I would take it in a large and consider a small. Please oh please help me score this lovely.

Probably a size 10 but I can do a 12...possibly an 8 if it fits generously. 

I think I need this one in a Large, but would consider a Medium.

I loved this blouse when it first came on line but sadly the price was ludicrous in the $200 range from what I remember so I put it out of my mind. And missed the markdown price. I think I need this in a 10 but would consider it in a 12.
