Aster Diamond One-Piece Swimsuit

Product Insights & Style Tips

Zimmermann's Aster Diamond One-Piece Swimsuit reads resort-luxe gloss, with a colorblock silhouette and a central diamond cutout at the bust that instantly reads flirtatious and refined. The V neckline depth flatters while the shiny swim fabric—nylon, polyamide, elastane—catches the light as you move. Adjustable straps let you fine-tune the sit of the cups, and side seam boning hints at sculpted shape even before you step into the sun.

With mid-back clasps and the sculpting side boning, the suit holds its line from the moment you step onto the deck to the moment you relax on a lounge chair. Available in size 0 through 3 (XS–L), it fits with Zimmermann ease. Moderate seat coverage keeps things in balance, while adjustable straps let you dial in lift and angle. It layers beautifully with a sheer sarong or a crisp white shirt thrown over for a pool-to-slip-dress transition; the glossy fabric moves with you, never losing its cool, refined edge.

Aligning with Zimmermann's signature romantic resort codes, Aster feels at home in seaside picnics and rooftop bars alike—an elevated one-piece that doubles as a statement base under a sheer cover-up or as the main event with gold hoops and a wide-brim hat.
