^ Susanna, as you may know, we have several Polyvore competition threads here in Personal Style ... you might check those out. They're mostly if not all on the front page of the forum.
^ Trendspotter, we're not so much about trendy dressing here in Personal Style as we are about discovering and implementing our own personal style, and fitting trends to that.
If you're interesting in trends, you should check out our Trend Spotting forum. If you're interested in personal style, our Starting the fashion thing thread is a good place to start.
