Simple design black blazer jacket with hidden buttons and a stand-up collar, three-quarter sleeves. - Color: Black - Design: Features 4 hidden buttons, pockets on both sides. - Sleeve Length: Three-quarter sleeves - Collar Style: Stand-up collar - Back Design: Fitted at the waist - Material: 97% cotton, 3% polyurethane (stretch material for ease of movement), unlined - Size: L, Length 55cm / Shoulder Width 41cm / Sleeve Length 44cm / Body Width 48cm (Slightly small for a size L) In the 90s, I used to wear this as a light outer layer in spring and summer, unbuttoned for convenience. Unlined, three-quarter sleeves, cotton material, and a black jacket. This single item is perfect for protection against air conditioning in the summer, shielding from the sun, and providing a sense of security even when wearing sleeveless tops, making it suitable for formal occasions. I would be happy if someone who appreciates vintage items could reuse it. Thank you for looking.
