Features and Construction

This shirt is defined by its specific design elements and material composition, which contribute to its overall look and feel.
Material and Build
The primary construction material is 100% polyester fibre. This synthetic fabric is known for its durability, resistance to wrinkling, and ease of care, contributing to a garment that is low-maintenance and holds its shape well through wear. The choice of polyester supports the shirt's lightweight character, making it suitable for layering during autumn or for indoor wear where a heavier fabric might be less comfortable.
Size and Practical Fit
The shirt is offered in a comprehensive size range: S, M, L, XL, 2XL, 3XL, and 4XL. It is crucial to consult the size chart before ordering, as the sizing follows Asian standards, which typically run 1 to 2 sizes smaller than European or American equivalents. If your measurements fall between two sizes, selecting the larger option is advised. A tolerance of 2-3cm in measurements should be expected due to manual measuring processes. The design features a 'Loose' version style, providing a relaxed fit through the body, coupled with a 'Slim' overall description that suggests a tailored, non-baggy silhouette.
Uses and Placement

With its specific style cues, this shirt fits into both casual and slightly curated fashion contexts.
Event or Professional Use
The Korean style influence, often characterised by clean lines and modern cuts, paired with the Japanese retro element, gives this cardigan-shirt hybrid a distinctive look suitable for casual social events, creative work environments, or days out where a smart-casual aesthetic is desired. The range of colours allows it to be paired with neutral trousers or jeans for a cohesive outfit.
Everyday Home Use
As a cardigan-style shirt, it functions well as a lightweight layering piece for cooler autumn days at home or for running errands. The polyester fabric offers easy care, which is practical for regular wear. The loose fit prioritises comfort for extended periods, making it a practical choice for relaxed, everyday scenarios without sacrificing a considered appearance.
Benefits and Buying Value

The value of this shirt lies in its combination of style, fit options, and practical fabric.
Reuse and Low Maintenance
Polyester as a material is generally resilient and easy to care for, often requiring minimal ironing and drying quickly. This supports the shirt's potential for repeated wear across seasons with straightforward washing, aligning with a practical, low-fuss approach to wardrobe management.
Why Choose This Product
This shirt presents a clear choice for those seeking a specific style intersection—Korean fashion with a retro Japanese twist—in a cardigan format. The key differentiators are the explicit loose, slim fit, the four-colour selection, and the exceptionally wide size range up to 4XL, which offers genuine inclusivity. It provides a defined aesthetic without requiring specialised care, making it an accessible entry point into this style genre.
