I love my hangers. So much so that they adorn the wall in my little laundry room.
I thought about hanging the night gown from a puffy-type-lingerie hanger. Those are nice because they keep the garment from shifting. But they don't clang sweetly when bumped together. Neither do they reflect the light like chrome can. I also love the weight of these chrome hangers - something I hope will translate onto the canvas.
The hanger and gown will be back-lit in front of a window so I'm not sure how much reflecting the chrome will do. We'll have to see.
