This piece is made from 100% Polyester, a knit fabric that feels soft against the skin and allows for breathable comfort. The knit construction gives the piece a flexible, body-skimming quality that supports its slim fit, making it a natural choice for casual, everyday wear in autumn. The V-neck and long sleeves keep the look clean and easy to layer, while the solid colorway in navy keeps the aesthetic simple and versatile for daily outfits. The fabric has a regular thickness, so the piece works well on its own or under a light outer layer during the fall season. Its breathable, skin-friendly quality makes it comfortable for all-day wear, and the knit texture adds a subtle visual interest without feeling heavy.
