This piece combines two distinct fabric components for a balanced, comfortable wear. The main body fabric is a blend of 50% rayon, 20% nylon, 25% polyester, and 5% spandex, giving it a soft, stretchable quality that holds its shape and resists wrinkling through long days of wear. The second fabric, used for the striped shirt section and the neck and sleeve ties, is 100% cotton, chosen for its natural breathability and dry, comfortable feel against the skin. Together, the two materials create a textural contrast that supports the piece's French-inspired, retro-striped aesthetic while keeping it suited to everyday commuting and smart-casual occasions in autumn. The fabric has a regular thickness, and the cotton sections add a light, airy quality that balances the fitted, shape-hugging structure of the main body. The materials are skin-friendly and breathable, making the piece an easy choice for daily office wear and relaxed smart-casual settings.
