First-line brands such as Youngor, the regular price is set at 3000-5000 yuan. The discount is around 1500. It is estimated that it will be more expensive if customized. But the single set depends on the store, and many of them are customized without a single set. Pei Luocheng is also a well-known trademark in China, and the price is similar.
If you are not very sensitive to the brand, you can try Baidu's "suit base", a professional suit customization mall with 70% wool of 799 yuan, aiming at self-cultivation and cost performance.
