Satin train - how to get a good shape?

deannemuso

I've bought a dress where I love the front but am wondering how to alter the train to get it looking nicer. I want a bit of 'poof' at the back - not just going all floppy. Am going to shorten it but don't know by how much. Has anyone had a satin wedding train altered? Would love some pics of different lengths and how it looked from the side. Has anyone added any decoration to the train? It looks particular strange in the pic because the dress was pegged smaller for me.
