I know several places that sell cheongsam for reference only.

Xidan 109 wedding dress building has wedding dresses and ready-made clothes, but there may be no small ones, which can be customized, and some are more expensive.

Tai Sen International, a newly opened place similar to 109 wedding building, has ready-made clothes that can be customized at a price similar to 109.

Xiushui street, you can order cheongsam, the asking price is more expensive, you can bargain, you must bargain.

Wukesong Photography Equipment City, mainly aimed at newcomers, can order cheongsam at a price slightly lower than 109 and Tai Sen International.

There are also some clothing production studios, some of which are relatively high-end. There are also students who have just graduated from clothing colleges, aiming at the low-end market.

Personally, if it is used for performance, it is not such an important occasion as the Spring Festival Evening. On the whole, it is enough. What the performance cares about is the stage effect, not the comfort of the clothing itself, so there is no need to make silk fabrics, and the workmanship can be less strict.

Recommend two studios, aiming at high-end and low-end respectively.

Ma Yanli advanced clothing studio. People who make clothes must know Ma Yanli's name. He explained it to them and made it for many stars. Good technology and high price. The address is in the south of Fangcao, Han Wei Building. I forgot my cell phone.

There is also a studio that has handled it, all of them are young people who graduated from fashion colleges. The workmanship is OK, but it is not as good as that in Ma Yanli, and the price is much lower. The address is in the East Third Ring Road. I know QQ284889658.
