Antonia Sheer Beach Poncho – Cinnamon
The layer you’ll wear long after you leave the beach.
The Antonia is cut from premium sheer fabric in Cinnamon, a warm, sun-baked brown with rich red undertones. Designed with an asymmetric neckline, dramatic draped sleeves and a fluid, flattering cut, it brings an effortless finish to whatever you wear underneath.
Throw it over your bikini by the pool, then style it with shorts or trousers when the sun goes down. Lightweight, beautifully made and far too good to save for the beach.
