I just received this outfit, mailed from China, and it is absolutely beautiful. The navy/royal blue color is exactly as shown in the photo. It is 70% rayon/30% silk. I don't read Chinese, but the percentages are on the tag. The fit is perfect. I ordered a medium because they didn't have a small, and I'm glad I did. I wear a dress size 8 and their medium fits me perfectly: arm length, shoulder width, pants length -- all as though custom made for me. I washed it in cool water, delicate cycle, and put it in the dryer for 10 minutes on delicate. It came out without any shrinkage and without any wrinkles. I couldn't be happier. I know the shipping is terribly expensive, but in this case it was worth it.Update: the body of the jacket and pants, I believe, are 100% rayon or polyester. The only silk in the garment seems to be the inner white cuffs on the jacket which fold back and out. I don't mind, really, since it keeps the outfit from shrinking, but if you are looking for silk, you may want to rethink your purchase. Also, where the seams in the legs meet is a bit rough. Otherwise the outfit is very comfortable. One more thing...don't try to sleep in this outfit. Because it's not real silk, it is overly warm. I am still happy that I purchased it, but I wish it were real silk.
