Features and Construction

The sweater's construction centres on a hollow knit technique that creates a medium thickness fabric without excessive weight. This approach balances coverage with breathability, while the batwing sleeve design extends from the body to create a distinctive silhouette. The loose fit version accommodates various body types through its free size designation, though specific chest, waist, or length measurements are not provided in the available data.
Material and Build
Constructed from polyester fibre as the main fabric composition, this sweater utilises synthetic material without additional natural fibre blends. The hollow knit technique creates air pockets within the fabric structure, contributing to the medium thickness specification. Thread elements incorporated into the striped pattern add textural detail to the garment's surface, enhancing the visual retro rainbow colour scheme without altering the base material properties.
Size and Practical Fit
Available in a free size designation with a loose fit version, this sweater accommodates various body dimensions through its generous cut rather than precise measurements. The batwing sleeve construction extends from the body without traditional armhole seams, creating a draped effect that complements the loose silhouette. While specific dimensional data isn't provided, the medium thickness fabric maintains structure without becoming bulky, supporting the casual Japanese Korean style aesthetic.
Uses and Placement

This striped sweater serves as a versatile single-piece garment suitable for multiple casual contexts. The retro rainbow colour palette and striped pattern provide visual interest that can stand alone or coordinate with simpler complementary pieces. The hollow knit construction offers moderate warmth without heavy insulation, making it adaptable to various indoor environments and mild outdoor conditions.
