🌺 Rectangle Body Bikinis – Curve‑Creating, Waist‑Defining & Shape‑Enhancing Fits

Rectangle bodies typically have:

  • Create the illusion of curves
  • Define the waistline
  • Add volume to the bust and hips
  • Break up the straight silhouette

Sunnybikinis rectangle bikinis are designed to sculpt, shape, and add dimension.
