Laura, I ( from someone who just fell off ) I agree with Kristen. Don't do it for a Halloween costume. You have alternatives.
And I don't believe it is ego either. The Buddhists believe that the reason for so much human suffering is desire. ( That is why I am not a Buddhist - I can't kill wanting things....I would rather just go to confession and get absolved ; 0
You question is such a complicated one. And it is generations of conditioning and living in a society where 70 % of our GDP is BUYING !
Finally, this is a work assignment, so I would try to hang in there as much as possible. I like Kristen's idea of writing about it. Don't be ashamed : this is how we live today. You might want to look up Paco Underhill. A BRILLIANT economist, who, unfortunately, has spent his brilliance figuring out how to convince to buy, buy, buy ! And it works, works, works !
PS YOU ARE SOOOOO FREAKIN' CUTE, that a new black dress couldn't amp it up any further !
