If you are in Shanghai for at least 5 days I HIGHLY recommend you plan this FIRST. You will not be sorry. First thing I did when I arrived on Sunday was head to this market. I specifically made sure to tell the dressmaker that I was leaving Friday. Normally you can ask for a fitting in between but since I was on a work trip I only had time to pick up the final piece Friday. I did some research before & printed out photos a tunic and a dress I wanted made. Stall: 238 on the second floor Cost: 500 RMB for both (Don’t forget to bargain). Not a bad price considering I got two well made pieces that fit me perfectly. This is not common for me since I am tall. If I had been more prepared I would have brought my favorite dress that I grew out of and asked for a new one in a different fabric. I also would have bought some expensive jeans, kept the tag on, had them make a copy and then return the originals when I got back home. Just a tip in case you can manage this.
Tip: -There are food stalls outside of the market and I HIGHLY recommend that you get the scallion pancake. You can get it with or without meat and spicy or non spicy. It's a very inexpensive snack.
