You could put the centre panel on the back and use the borders round the bottom or edge of the sleeves - you'd need to find some similar silk of an appropriate colour to do the basic shirt in. Maybe.This is a piece of Versace silk on ebay Venus of Botticelli 100% Silk Fabric, Made in Italy | eBay. I'd love to have it as a shirt but I can't see how to make it work. It's 140 cm square, so I suppose the central painting part is about 50 cm square. I've got a couple of Versace silk shirts which I'm very attached to.
You really should go and look at Simply Fabrics in Brixton as I think you're local. They get all sorts of deadstock/overruns, some of which is ex designer. I've had some fabulous fabric from there.
