This is a TOMORROWLAND men's polo shirt, the "Silk Cotton Knit Polo Shirt SESIA," made with the finest silk and cotton. It originally cost around 30,000 yen (retail price ¥29,700) and is a new model from 2024. It's still available on the official website for just over 20,000 yen after a discount. The color is yellow, but it's a subtle, slightly muted lime yellow, in a good way. It's a summery, vibrant color that doesn't stand out too much, yet still looks stylish. It's in beautiful condition, having been worn only once. The material is high-quality, and the pattern is designed to be three-dimensional so as not to restrict shoulder movement, demonstrating attention to detail throughout. Here's the description from the official website: This knit polo shirt is made from a silk (55%) and cotton (45%) blend from the Italian company, SESIA. It features a smooth texture and a deep, melange-like color. The silk's luster and the vibrant colors of the Italian dyes are appealing. It has a regular fit that's easy to style in many ways. The three-dimensional design of the shoulders and sleeves creates a sleek silhouette when worn. It has an elegant look with a collar that aims for volume and a good roll. Official size: S; Length 62cm / Shoulder width 36.5cm / Body width 48cm / Sleeve length 27cm
