    I'm a Fashion Editor and First-Time Mom-to-Be—Sézane's Newborn Collection Is My Baby Shopping Obsession

    The brand took my favorite pieces and remade them for the littlest fashion lovers.

    The news hit my fashion mom group chat faster than you can say "The Row sample sale": Sézane is releasing a newborn collection.

    The lineup of teeny-tiny cardigans, rompers, and knit booties sent the parents I know into a frenzy, alongside thousands of other moms I saw in the brand's Instagram comments, when it went live March 8. While Sézane has complemented its French-girl essentials and limited-edition collaborations with the Petit Sézane children's line for a few years now, it's never offered clothing for the bittiest fashion kids. (That is, newborns in sizes 0-6 months old.) As a first-time mom-to-be who's also a vocal fan of Sézane's trench coats, sweaters, and takes on trending shoes, I couldn't resist stocking up on a few Sézane pieces for the baby, too.

    In a press release, Sézane describes the lineup as "everyday essentials crafted with care." In a preliminary "Add to Cart" session, I saw this take shape as miniaturized versions of my most beloved Sézane pieces, like the button-front Gaspard cardigan and the flouncy Heloise shirt. My cart also filled with little extras that will make adjusting to a new, baby-centric normal more fun: a spacious gingham diaper bag, a patterned sun hat, soft, printed swaddle cloths.

    While I've so far stocked my baby's nursery with no-frills onesies and socks, I'm enamored with the chance to make newborn dressing more of a mother-daughter moment. Of course, it's not only moms who can appreciate this launch: If someone in your life is expecting, these considered, B-Corp certified knits and onesies make a thoughtful (and chic) baby shower gift.

    Below, I've shopped out the Sézane newborn items that already match my mom-to-be wardrobe, plus a few pieces headed for my own baby registry.

    Sézane Mom-Baby Matching Pieces I'm Shopping

    I have to start with the Gaspard cardigan, a Sézane classic I already style in gray, cream, and black on the regular. I'll pick out a colorful sea green or pink for the baby, then add another to my collection in a matching shade. Having owned this sweater for several years already, I know both our knits are going to last.

    Next up? A little boho baby moment. There aren't one-for-one matches between Sézane's newborn shirts and the blouses for moms (yet), so I'll get started with these color-coordinating tops. On the newborn shirt, the ruched neckline and sleeves are flexible for easy changes.

    After hearing from other moms about the wonders of shackets, cardigans, and other easy-front-access tops for breastfeeding and pumping, I ordered Sézane's Betty top for my postpartum wardrobe. (I'm also wearing it now, just half-buttoned over my bump.) Seeing there's a little baby version for layering at chilly appointments and walks in the park made me even happier I already have one in my closet. Think of the matching opportunities when we're ready to go out!

    Anyone who reads The A-List Edit, my Marie Claire styling newsletter, knows I love ballet flats in every form, color, and material. Naturally, I think Sézane's itsy-bitsy Mary Janes, in a collaboration with Vibi Venezia, are a perfect fit—for my own first-born, and to gift other new moms who appreciate a cute shoe.
