Best-Dressed List: Jessica Alba Is Peachy And 11 Other Stylin' Stars This Week (PHOTOS)

We don't know about you, but we get pretty lazy around this time of year. Getting dressed for and in this heat is an event worthy of an Olympic medal. Which is why we usually default to some variation on the loose dress -- no complicated, heat-trapping layers and nothing touching our skin.

It would seem some of our favorite stars have resorted to the same methods. First of all, we're ready to just be Michelle Williams already. If anyone has ever made a pixie cut look so cute, well, we challenge you to point them out in comments. But we're also really feeling the summer shifts she's been walking around in all summer long. And that straw bag.

A lot of other actresses joined her in the loose dress department -- and then there was Jessica Alba and Mischa Barton who did a little suiting up. Behold, this week's air-conditioned best-dressed list below. For a more sobering look back at the week in (non-)style, check out our worst-dressed list.
