Polly is the lightest, most fluid Parker yet: a pale cornflower-blue jacket with a softly gathered keyhole neckline that fastens at a single button, rather than the stand collars seen on earlier pieces in the family. Its sleeves are the standout, full bishop shapes that balloon out from the shoulder before narrowing into a gathered cuff at the wrist. At the waist, a slim tie belt cinches the shape before it releases into a ruffled peplum hem, giving the jacket a softer, more blouson silhouette than a strict outerwear cut. It layers just as easily over separates as it does over its own matching trouser. For a version with more contrast, try it over the Palazzo Pants in aubergine.
