Where to get a suit in Beijing around 19th- 30th January…

Hi, so me and my fiancé is getting married this summer. He will be travelling to China the 19th and we would get to a tailor to find him a suit. However the tailor I wanted to visit says he will be closed due to Chinese new year holidays. We didn’t expect the shops to close down for a month tbh. Do anyone know a tailor that can help us or where to get a suit? This is horrible news and it’s very important
