Sirena One-piece

Magnetic, fluid, and unapapologetically powerful.
Sirena is a sculptural one-piece designed to move with the body and command attention from every angle. The wrap-style halter neckline crosses and frames the bust, while cut-out detailing defines the waist and elongates the silhouette. Statement ring accents draw the eye and add a confident edge without overwhelming the form.
Sirena is made for bold swims, slow walks to the water, and moments where confidence becomes instinct.

PRODUCT CARE

At Ban-dia, our swimwear is handcrafted in the UK using high-quality Italian and UK-made fabrics, carefully selected for their beauty, performance, and longevity. Each piece is designed with the intention that it will remain stunning season after season.To preserve the look and feel of your Ban-dia swimwear, please follow these care guidelines:

  • Rinse immediately after wearing
  • Do not scrunch or twist when wet
  • Hand wash gently using a mild detergent
  • Avoid fabric softener
  • Reshape while damp and lay flat to dry
  • Dry in the shade
  • Do not bleach, iron, tumble dry, or dry clean
  • Take care when using sun cream, lotions, oils, or in chlorinated water, as these may cause discolouration to some fabrics

Our swimwear is designed to flatter a range of body shapes, with many styles offering adjustability rather than a single fixed fit. Crafted using stretch fabrics and thoughtful pattern cutting, each size allows for comfortable movement, gentle support, and a naturally flattering silhouette.
If you find yourself between sizes, personal preference can guide your choice:

  • Choose the smaller size for a more supportive, close-fitting feel
  • Choose the larger size for a more relaxed and comfortable fit
Every body is unique, and fit can also be influenced by how you prefer your swimwear to sit. If you’re unsure which size is right for you, we’re always happy to help. Simply get in touch with your measurements and we’ll advise as best we can.
