I have a two-part answer to your question, the first in direct response to the question asked and another concerning consumerism in general.
Things can not define you. Even the thoughts in that pop up in what we Buddhists call your Monkey Mind do not define you. Only your actions define you. The decisions you act on and the way you act and talk to people and other sentient beings are the only defining characteristics of you. You can dress yourself like a Hawaiian native, but if you are, lets say, of Northern European descent, you are no Hawaiian.
The Buddha was extremely clear that material things can not bring lasting happiness. Therefore he challenge us to look at everything we desired to see what is the root cause of this desire and what the affect will be to giving in. When one looks at the pattern of desire and happiness we can see that it is obvious that we have a short, finite impulse of happiness when we purchase something we want, but that happiness does not last and then we race towards the next thing that we think will bring us happiness.
