Casual shirt with a navy floral design. - Design: Floral - Color: Navy - Material: Polyester - Style: Casual - Sleeve Type: Long sleeve Thank you for viewing. It's rayon, but not flimsy; it feels slightly stiff. The condition is good, and the collar is also firm. It looks great worn alone in the summer, or as an inner layer under a jacket in the fall and winter. It's a stylish piece on its own.
