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)Yet just as some educators believe that single-sex classrooms are better for learning, some luxury brands are finding that single-sex stores sell better. The trend of opening stores for men only took off two years ago. Now more brands are catching on.

Even luxury brands already strongly associated with menswear are paying more attention to their retail space, trying to create a private club environment.
