The piece is made with a face fabric of 100% PU, giving it a smooth, structured surface suited to its original design and slim-fit silhouette. The fabric back combines 95% viscose with 5% metallic fiber, adding a subtle sheen that complements the three-dimensional decorative details and the U-neck, zip-front styling. Its thin, soft construction and non-stretch feel make it appropriate for daily wear and layering in summer. The lining is 88% nylon and 12% spandex, offering a soft, slightly stretchy interior that moves comfortably against the body. Together, these materials support the piece's original, slim-fit aesthetic for everyday summer occasions.
