A fresh twist on a signature silhouette – meet ‘Agatha’.
This elevated knit top brings corset-inspired structure in the most comfortable way. Made from a soft, ribbed stretch fabric, it hugs the body gently while flattering every curve. The sweetheart neckline and long sleeves create a graceful shape, while the front is detailed with hook-and-eye closures for a subtly cinched effect. Delicate picot trims add a feminine touch along the neckline and hem, softly framing the shoulders and hips.
HOW TO STYLE:
Pair it with our ‘Eliane’ skirt and a tailored blazer for a polished look that transitions seamlessly from day to evening.
