It is very doubtful that many clothes will not be brushed in sister clothing stores at first or the probability is extremely low, and will only be brushed after you have the first or even more clothes.

For example, I bought two pairs of outdoor sandals mentioned above and brushed them in a clothing store. On another occasion, I received two clothes of dwarfs, which were quickly brushed in a clothing store.

It is suspected that when you have two different colors of the same kind of clothing, the probability of clothing stores brushing out this kind of clothing will increase a lot. Of course, it is also possible that I hacked from the beginning.
