A、Because Asian men’s potential for purchase hasn’t been developed. B、Because the rich Asian men don’t have to hide their wealth

Some luxury brands have always aimed exclusively at either men or women, but most are happy to promote their stores to serve both sexes. (33)Having noticed that the single-sex classrooms are proved to be better for learning, some luxury brands guess that single-sex stores may sell better. The trend of opening stores for men only took off two years ago. Now more brands are catching on. Men can be very loyal customers, supporting their favorite brands more than women do, but they also tend to adopt a hunting attitude toward shopping. Men like to hunt, while women gather. Men will set out on a shopping expedition with a clear, specific goal in mind, and once they’ve found what they want, they quickly leave the crowd. Women are content to spend hours searching, often with no clear goal. (34) But give a man a retail environment where he feels at home—or even more comfortable than he does at home—and you’ll keep him there longer, and almost certainly sell him more. Even luxury brands already strongly associated with menswear are paying more attention to their retail space, trying to create a private club environment. The men-only concept store is likely to expand as luxury firms pursue male spending power in emerging markets, particularly in Asia. (35)"And now that the rich Asian customers aren’t under pressure to hide their wealth, men with the spending power are really treating themselves and visibly enjoying the fruits of their success," says Barker.
