When I glamor I tend to pick what I like and what looks good, sometimes it's very similar to what others are wearing. Most times tho it is rather unique and I don't see many other people wearing the same thing as I am. In any case it all depends on what each person personally likes on their char.

The second something new comes out you know everyone is going to have it because it's new. When the Thavnairian bustier came out and people were able to start making them pretty much everyone was wearing them, same as when Minfillia's outfit was added to the mog station and so on.
