Yep, wearing all one color. We love this trend for a couple reasons: It's super easy to put together (since you don't have to worry about whether or not one color goes with another), and it's incredibly flattering and leg-lengthening.
Dressing in one shade creates a long line from your head to your toes and makes you look taller automatically. (And yes, this works for any color.)
Take Meghan's ensemble above: Had she paired her silky, dark green button-down with a leather pencil skirt in, say, navy, it would cut her off right at the waist. By matching her top to her skirt, she's creating a streamlined silhouette that creates the illusion that her body is longer than it actually is.
Thanks for the tip, Meg.
