There are several foreign trade garments near Dongguan Street. I usually buy it there, and the waist circumference is usually over 3' 5.

Take bus No.30, 1 1, 106, 1 12 and get off at Dongguan Street Station, just north of the road.

Of course, there are foreign trade clothing stores nearby, and the price is not expensive.

There is also a store specializing in fat pants in Luokou New Store. I forgot my name. You can look for it.
