When Kate Middleton stepped out in a red Preen dress [1] during her trip to Canada, our mind immediately went to Princess Diana. The design was supersimilar to something the late royal wore back in 1995 that we considered it a tribute, but little did we know, the pleated midi was actually a style-star favorite. It turns out that Kate wasn't the first to wear this feminine piece: Emmy Rossum rocked it mere days before the duchess while celebrating her bridal shower.

Instead of opting for drop earrings, adding a pin, and wearing matching red shoes, the actress went simple with the styling. In fact, Emmy added zero little extras — except for her stunning engagement ring [2] — and completed her look with neutral, beige sandals.
