My overall favourite foundation, the Smashbox Studio Skin 15-Hour Wear blew. Me. Away. The formula is PERFECT: it covers everything, it feels amazing on the skin (never oily!), and transfer is minimal. Plus, it really does last hours and hours. I wore the stuff when I went on holiday in Vegas, and by the end of the day, my skin was very nearly as flawless as when I had first applied it. Not to mention, I was obsessed with the way it perfectly matched my neck (this line also has a shade for warm-toned fair skin!).
