Gaucho-inspired headwear featured pretty heavily in campaigns by Chanel in 2010, so I might be a little late in saying that this is a pretty sweet way to protect your face from the (murderous, Irish hating* Australian) sun. Malene Birger has whipped up a relatively inexpensive way to satisfy your South American inclinations with her Ytila hat in black- $85 USD plus shipping from lesnouvelles.com. Yes, yes and yes some more.
*I say this as the benefactor of milk-white Irish skin- completely impractical when one considers my proximity to that supposed ozone hole. Awaiting the melanomas.
