There are so many gorgeous sets out there. There are also so many beautiful pieces in those sets that are light years beyond my price range. I'm trying to use affordable pieces, many of which I actually own, to create sets for myself and anyone else that loves to draw inspiration from high dollar designer pieces, but whose budgets are closer to Earth.
One challenge this presents is finding good pictures to use for polyvore. I suspect that the reason some $$$ items are used is simply because it's a good picture - a good silhouette (a $495 white oxford shirt? really??) where the Macy's $30 shirt is an impossibly posed model. If you occasionally see a pricey pair of black slacks or blue jeans or t-shirt, please know it is only there as a placeholder for your own version of the same generic article.
