I'm convinced chambray shirts look good with just about anything; I can see one paired with any of the striped skirts below. As for the knotted part, it's not a trend I would invest in (aka buy a shirt that is already knotted), however, I do enjoy knotting a shirt I already own. It works particularly well with this skirt, because it's hard to tuck a shirt into a stretchy cotton skirt without it bunching up and showing through. Have you tried the knotted shirt trend? Store-bought or DIY? 

Skirt: Limited, $25

Purse: Emma Fox c/o Ross, $60 ( similar, I also spotted the same bag at TJ Maxx this week!)
