Ballet-Inspired Grace. Everyday Function.
We added the Charlotte to the Heyday edit because it does something most maternity pieces don't: it looks like an outfit, not a workaround. Made in New York City, the Charlotte offers a beautiful silhouette that honors your ever-changing body with buttery-soft comfort. Whether you're on a weekend city stroll or dressed up for a celebration, the Charlotte moves with you, blending the grace of a ballerina with the practical needs of pregnancy and nursing.
The Details:
The Signature Shoulder Bow: attached grosgrain shoulder bows that are entirely size-adjustable. Go big and bold for a statement look, or keep them small and sweet for a morning of errands. You're in control of the silhouette.
Breathable Lenzing™ Modal: eco-friendly modal gives the Charlotte a second-skin feel that stays cool against the skin, with the effortless stretch your evolving shape needs.
Intuitive Nursing Access: hidden functional front snaps give you quick, easy access for nursing or pumping without sacrificing the dress's sophisticated, streamlined look.
Pregnancy & Beyond: from the first trimester through postpartum, this dress is a true style-meets-function staple. The fluid drape adapts to your rhythm, so you feel as polished as you do comfortable.
Product Info:
Composition: 92% Lenzing™ Modal, 8% Spandex. Exclusive of decoration.
Craftsmanship: made in New York City's Garment District.
Care: machine wash cold on a gentle cycle, turn garment inside out. Lay flat to dry to preserve the luxury feel. Cool iron if needed.
Sizing Note:
We recommend starting with your pre-pregnancy size.
Our fabric offers generous, high-recovery stretch. If you prefer a more compressive fit, we suggest sizing down.
