x REVOLVE Opal Skirt

This mini skirt features a sheer, tulle-based construction defined by vertical satin-ribbon detailing that creates a subtle, undulating wave pattern. The scalloped hem provides a soft finish to the sharp, 14-inch cut, grounding the high-octane glamour typical of Costello’s aesthetic in a clean, ivory-beige palette. It is a structural piece that reads more like an architectural overlay than a traditional skirt, best paired with tonal layers to emphasize its linear geometry.

Safety Rating: Lowest

Analysis: The garment is composed entirely of polyester and elastane, both of which are petroleum-based synthetic polymers. These materials offer low breathability and may trap heat against the skin, while synthetic fibers carry a higher risk of microplastic shedding and potential chemical leaching during perspiration.
