A bandeau one-piece swimsuit is a type of swimsuit that covers the torso and has a band of fabric that goes around the bust and back, rather than traditional straps. It is similar in shape to a tube top, with a straight or slightly curved top edge that fits snugly around the chest and a lower edge that sits at the waist or hips. Bandeau one-piece swimsuits often have removable straps for added support and can be worn with or without them. They are a popular choice for swimwear because they are comfortable and offer a flattering, streamlined silhouette.
Bandeau one-piece swimsuits are often made with stretchy, form-fitting materials and may have built-in cups or padding for support. They are often worn by people who want to achieve a smooth, streamlined silhouette and may be particularly popular among people with smaller busts or those who want to avoid tan lines. Bandeau one-piece swimsuits can be worn for swimming, sunbathing, or participating in water sports.
