That dress in Hangzhou is very expensive. I don't know where you come from. If it is from the north, you'd better not go. The clothes there are too small for northerners to wear Shirts are generally 30 to 40, short skirts are 40 to 50, and coats are 90 to 100. In short, they are very expensive. As for the scale, there is no requirement. You can take one or two. It's just too expensive, and some are more expensive than retail.
