Women's Aster Diamond Wire One-Piece Swimsuit

Product Insights & Style Tips

The Zimmermann Women’s Aster Diamond Wire One-Piece Swimsuit is pure poolside glamour, delivering a hit of sultry structure with its sculptural diamond-wire neckline. The neckline plunges and frames like a modern corset, yet the piece keeps just the right amount of softness in its stretch fabrication—a blend of polyamide and elastane that gives a sleek, second-skin feel. The interplay between gleaming architectural hardware and the fluid ease of the silhouette lands at the intersection of Bond-girl allure and signature Zimmermann romance, radiating a sense of straight-off-the-yacht confidence.

This one-piece moves with the body thanks to its adjustable straps and resilient, smooth fabric that hugs but never restricts. The open front and diamond detail draw the eye upward, while the coverage and lined interior ensure it’s as flattering as it is striking poolside or under a sheer skirt for cocktails after sundown. The pull-on fit eliminates fuss, and the structure at the neckline stays crisp through dips and lounging alike, making it a swim piece that slips easily from swim to après-swim moments. Zimmermann’s hallmark is always a nod to effortless fantasy—the Aster Diamond swimsuit is a clever evolution, blending architectural accent with that unmistakable languid Australian ease.
