x REVOLVE Zosia Corset Top

This Michael Costello bustier leans into high-voltage geometry with a sharp, pointed hem that anchors the torso. The construction relies on a structured, boned bodice and underwire cups to maintain a rigid, sculptural shape against the chest. It is a hyper-saturated piece of evening wear that prioritizes architectural precision over soft draping.

Safety Rating: Lowest

Analysis: The garment is primarily composed of a cotton-viscose-elastane blend, but the inclusion of a polyester lining—a petroleum-based plastic—brings the overall profile into the lowest category. The reliance on synthetic lining and elastane for stretch reduces breathability and increases the likelihood of moisture retention and microplastic shedding against the skin.
