alike

I went to a shopping mall today, the larger in Buenos Aires. I didn't buy anything, but noticed that all women in their thirties or so looked all alike: jeans, t-shirts and vests. Is there any fashion style I'm not aware of? I shouldn't forget to tell you that they did have the same hairdo.

I can't include myself in such a wonderful trying-to-look-like-teens group, as 1) I didn't have neither a vest nor jeans on, 2) I had my hair cut last week. Besides, I don't like being like everybody else (and I'm proud of being 33).

Is it me or is there a global tendency for women to look similar?
