Which piece of Kate Bosworth's is under $100? My first guess was that denim vest. I happen to know that gorgeous scarf is a Louis Vuitton piece that retails for $980, which is pretty steep. So I'm guessing it's not the scarf. If you guessed the skirt, you're correct! Kate rocks a $70 mini from Matthew Williamson's diffusion line for H&M. My guess is that most H&M stores are sold out of the piece by now, but it's definitely worth a try! If not, it's possible the store has other metallic minis in stock.
