Why are Givenchy's short-sleeved T-shirts so expensive that each one costs six or seven thousand …

That's because you saw it in China. As far as I know, gvc short sleeves, which are generally cheap, can be bought abroad in the early 2000s, that is, the main theme of this spring and summer is only about 4,000, and the number of pearls may be around 10000. The price depends on the styles you look at, but most of the beautiful ones generally don't exceed 4000.
