The package arrived on time. I did not communicate with the seller. The label says Polyester, but it feels like cotton. The quality is good. The dress is exactly the same as in regular city stores, but 3 times cheaper. The color matches the picture +/- shade.
I ordered size S for my EU 36 (RU 42), I was worried it would be too big, but it's VERY loose and I will wear it with a belt. For a height of 172 cm, the length of the dress is slightly above the knee.
