It's time to square your edges, people. According to the runways, boxes are your new best friends. Love them, treat them well and they'll reward you with hip points. Here's some of Spring's four cornered offerings:
Dries van Noten gives the grid a go.
Yves Saint Laurent's square conditioned coat and boots.
Francisco Costa's cubist collection for Calvin Klein.
Squares are super DIY friendly. Head on over to the office supply store, grab yourself a straightedge and start lining things up.
