I'd say it's more or less new, to be honest. Is it silk or synthetic? I had a synthetic long cheongsam (I just sold it - the slits on the side were just too high for my taste), with same flower pattern, but in dark blue with silver flowers. It was a pretty cheap synthetic one from a Chinese shop, and I must say the fabric, closures etc. looked pretty much like on yours. It also had a nylon zip and metal snaps underneath the ribbon closures. And I too had to buy a size L or XL to fit even my figure, due to Chinese sizes being so much smaller. I had mine from a Chinese shop in Vienna, and I have the impression they sell them by the dozen... But who cares if it's a mass-product, I think they look nice, even the synthetic ones, and with the right kind of styling, they're a nice addition to any wardrobe.
