Why? Because of pretending.
D&G bags are almost entirely marked with metal labels. The marks on clothes are also very small and sometimes very hidden.
If you never buy D&G and you see D&G at a glance, then that D&G is fake. Although D&G is not as good as DG (the DG logo is almost invisible, or not at all.) But D&G is also Not so obvious.
Most of them are imitations to make the trademarks look really big.
In fact, 90% of people buy that kind of D&G and don’t even know what it is when they wear it, because people who know it don’t know how to buy it, or are embarrassed to wear it, because they know that people who know it don’t know what it is. You can tell it's fake just by looking at it.
I have seen D&G in many cities in China, but think about it, an ordinary T-shirt costs more than 200 US dollars. Who would wear thousands of dollars of clothing and squeeze into a bus?
