I'm a sheep and end up buying things after I've seen them around or with regards to clothes other people wearing them or seeing them in magazines, but some people don't need to see them, they just know. For example a woman I know bought a white car a few years ago way before anyone else around here had one and has now got a dark coloured car, she had ash high tops again years ago way before they were everywhere. There are a few women and men around here who just seem to know what is going to be popular and buy it and then move on to the next thing just as most people are getting into the previous thing. Barbour jackets are another example of this, wearing them four years ago but not being seen dead in them now.
We're about as far from trendy areas as you can be so I want to know how do these people do it?
