Thea Gusset Maxi Dress in Classic Black
The Thea Gusset Maxi Dress is made for days and nights when you want to feel effortlessly graceful. Cut with a conservative round neckline that keeps things elegant, it skims through the bodice before opening up into a soft, full skirt. Hidden gusset panels add subtle volume and movement at the hem, so the dress swirls beautifully with every step and looks stunning in photos. Delicate trims frame the armholes for a dainty finish, while the light, airy fabric keeps you comfortable even when worn all day. Completed with an invisible back zipper for fuss-free wear, Thea is that easy, polished maxi you will reach for whenever you want to look refined without trying too hard.
