x REVOLVE Caisyn Gown

This gown relies on the tension between a deep, structural plunge and a fluid, side-split skirt. The midweight crepe creates a clean, architectural line through the torso, while the back cut-outs and spaghetti straps lean into the high-octane, red-carpet maximalism Costello is known for. It is a sharp, deliberate study in negative space and silhouette management.

Safety Rating: Lowest

Analysis: The garment is composed primarily of polyester and elastane, both of which are petroleum-based synthetic polymers. These materials offer poor breathability, trap heat against the skin, and are prone to microplastic shedding during wear and maintenance.
