Where in Suzhou are there many kinds of cheongsam with good quality?

The key of cheongsam lies in the material and workmanship. Personally, I recommend the wedding street over there in Tiger Hill. There is a bus to Tiger Hill at the railway station, and you can see it when you get off at Tiger Hill Station. Don't go to the shops along the street, because the rent is high, so the price is more expensive. I recommend some shops inside. I have seen cheongsam over there. The material and workmanship are very good, and the style is classical and trendy. I don't know the specific price I recommend. Maybe foreigners will kill you if they go. You can shop around and bargain everywhere.
