Stores on Douyin usually have many kinds of clothes, but whether clothes with three stripes can be sold depends on the cooperation between the merchant and the brand. Some brands may choose to cooperate with Douyin and list their products on Doudian, including clothes with three stripes. However, some brands may choose to operate their own e-commerce platform independently instead of selling their products on Doudian. Therefore, whether clothes with three stripes can be purchased on Doudian depends on the specific merchants and brands.
