Men's loose fit long sleeve cardigan shirt in Korean style and Japanese retro design

This men's shirt provides a distinctive casual look for autumn, blending elements of Korean fashion with Japanese retro aesthetics. Designed as a loose-fitting cardigan, it offers a relaxed silhouette suitable for various casual settings. The shirt is constructed from polyester fibre, a practical choice for everyday wear. It is available in a versatile size range from S to 4XL and comes in four colour options: classic black, crisp white, rich wine red, and deep dark blue. Potential buyers should be aware of the Asian sizing standard, which generally runs smaller than European and American sizing, and a slight variation in measurements due to manual sizing methods.
Features and Construction

This shirt combines specific design elements with practical fabrication to create its signature style.
Material and Build
The shirt is made primarily from polyester fibre, commonly referred to as polyester. This synthetic material is widely used in apparel for its durability and straightforward maintenance. The construction follows a cardigan style with a loose fit, contributing to the garment's relaxed and retro aesthetic as indicated in the source text.
Size and Practical Fit
The shirt is offered in a comprehensive size range: S, M, L, XL, 2XL, 3XL, and 4XL. A crucial note for buyers is that the sizing follows Asian standards, which are typically one to two sizes smaller than European and American sizing conventions. Therefore, selecting a larger size is recommended if your measurements fall between two sizes. A tolerance of 2-3cm in measurements should be anticipated due to the manual measurement process.
