The Maternity Cosima Nap Dress - Bluebird

$146.06 ~~$218~~ In stock

While every dress that includes our proprietary Nap smocking has some degree of flexibility, we handpicked our very favorite styles that work for maternity, postpartum, and beyond. Trust us, we have a lot of babies at HHH HQ.

A note to our Nap Dress Nation Besties: we didn't change anything to make this dress "maternity-friendly"; it's the same product you know and love. We just wanted to make it a little more clear to new customers with this separate page!

The Cosima Nap Dress
The Cosima Nap Dress is easy, breezy, and totally chic, featuring a fully-smocked (and bra-friendly!) bodice and a crisp, high boat neck fit. You can wear Cosima with flat sandals for a quick out-the-door look, or add a belt and statement earrings for a little something extra.
