It’s no secret that Chrissy Teigen is a style icon. But we just noticed something new—her maternity style seems to follow a very specific outfit formula: a midi or maxi dress, topped with a jacket or coat. The look is stylish without being uncomfortable. It adds just the right amount of coverage to flatter a growing figure. And the best part? You can utilize those non-maternity dusters and leather jackets you already own. While we may leave the sky-high heels to her (honestly, how does she do it?), we’re putting her maternity uniform to the test ASAP. Scroll down to see a few of Teigen’s style rules.

If You're Wearing a Fitted Dress, Pair It with a Duster

One of the joys of maternity dressing is suddenly having the confidence to rock those once nerve-racking bodycon dresses. In case you’re still apprehensive, a flowy topper like Teigen’s can act as a security blanket while also elongating your figure.

And Keep Your Pieces Within the Same Color Family

If You're Sporting a Flowy Dress, Pair It with a Cropped Jacket

Believe it or not, Teigen is well into her second trimester in this shot. Keep a flowy dress from becoming too overpowering by “cinching” your waist with a leather jacket and knotting the bottom of the dress to show a little leg.

Finally, Don't Neglect Your Weekend Wear

Even when working out, the Lip Sync Battle host keeps up her go-to formula. Tight spandex shows off her figure, and a cool moto jacket makes it appropriate for errands, brunch and the like.
