x REVOLVE Miki One Piece

This teal swimsuit relies on a high-cut leg and a sharp V-wire plunge to create a lean, aggressive silhouette. The metallic finish adds a liquid quality to the nylon-elastane blend, catching light across the torso to emphasize the structured, form-fitting construction. It leans into Costello’s signature high-octane aesthetic, trading traditional swimwear modesty for a red-carpet-adjacent intensity.

Safety Rating: Lowest

Analysis: This garment is constructed from a synthetic blend of nylon and elastane, both of which are petroleum-derived plastics. These materials offer minimal breathability and pose a higher risk of chemical transfer and microplastic shedding during use.
