Keira Knightley stepped out this weekend in pretty much the epitome of what we want to wear this summer -- a buttoned-up, flirty light blue Prada frock, paired with cool shades and a twisty hairstyle.

Another look we've been obsessing over is Keri Russell's structured white Monique Lhuillier crop top, expertly paired with a full black midi skirt. We predict you'll be seeing lots and lots of two piece ensembles as summer progresses.

Cutouts are still having a major moment, and we loved Jamie Chung in a teal Cushnie et Ochs, as well as Holland Roden in Paper London. Believe us when we say that expertly crafted holes in your clothes will still be around at the end of the season.
