When we first came upon the Kensington Royal Instagram feed [1], we couldn't exactly confirm its authenticity. But this morning, as Kate Middleton made her way to the Barlby Primary School to name its Clore art room [2], the royal account started to post photos — and a video, too!

We didn't only double-tap because Kate was showing off her baby bump on the social platform, we were also obsessed with her outfit! The fashionable mama-to-be was wearing yet another classic design [3]: the navy blue Naomi dress by Madderson London [4], complete with patterned, pink tweed panels and a complementing hem.

Plus, when we noticed she opted for dark opaque tights, an elegant clutch, and her go-to pumps, we realized the duchess had totally pulled off navy and black [5], a styling hack celebrated by all fashion girls. Scroll through to see Kate's most recent look from a few more angles, and then make sure you start following her [6] on Instagram.

The duchess received a warm welcome as she entered the Barlby Primary School auditorium.

Kate looked excited to accept the collage-covered chair. And we were equally excited to get a side view of her tweed-paneled sweater dress!

And She Accepted a Bouquet of Flowers, Too!
