Where is a physical store selling kimonos in Beijing?

There are about three physical stores in Beijing. I have been to the family in Andingmen. At 262, the door of the shop opens to the west. There is another one in Sanyuan East Bridge, whose door faces north. I can't remember the house number, and it is less than 100 meters away from Sanyuan East Bridge. These two families seem to be the same boss. There is another one on Xueyuan Road, the one on the third floor.
