Thank you guys for the links – I searched and searched recently for a show coat and had no idea the EA eventer coat came in super extra huge!! It might even fit ME! 
I have also just bought the Ovation Flex Field Boot and not only does the XXW fit me off the rack, it is a little big at the top. Love the stretch panel, and I might have been able to get away with the XW, but didn’t have them to try and compare. I have an 18" calf on the left and 17.5 on the right, but have a dip in at the top, and they were a bit big there.
I splurged at Red Hills, after spending a five days with my vendor booth next to the La Mundial vendor and ordered their custom boots. I had really wanted a dress boot and finally couldn’t stand it any more!
They should be here by June and I can do a report them as to how they fit fluffier riders.
Wheee!
