I bet that jacket she wore three days in a row was starting to get stinky, because the homewrecking hottie finally changed into something different yesterday afternoon.

We caught Sienna Miller walking her dog in NYC this morning, and we're happy to see that the blonde beauty has adjusted her attitude AND her wardrobe.
