A blue T-shirt from the French brand Petit Bateau, originally made for the French Navy. Made of ribbed material, it's stretchy, comfortable, and easy to move in, making it an undershirt. It's a very simple, plain undershirt and quite slim-fitting. The cotton material is smooth and feels great, and the Petit Bateau-style stretch makes it fit snugly against the skin. Although it's unused, it has been stored for a long time by a private individual, so I've listed it as "like new." Photo 5: The binder neck, a band-shaped rib, is sewn into the body of the shirt, increasing its strength. This specification is often used in vintage and military-style T-shirts. Photo 6: A separate piece of fabric is attached to the hem, like a large tag. Photos 7-10: Measurements are taken with a measuring tape. Please refer to them. Shoulder width 42cm, body width 44cm, length 69cm, sleeve length 21cm. Please note that there may be some errors due to the amateur flat measurements. There may be issues such as military items, deadstock, sun fading, knit damage, storage stains, dirt, and odors. The colors may differ from the actual product due to the photos. This information is based on research by an amateur on the internet, so there may be errors. Please purchase only if you can judge from the images and understand these points. military, military, army, royal navy, vintage clothing, actual item, release, uk vintage, British army, German army, Czech army, Swiss army, Belgian army, American army, RRL, Gurkha, Gurkha pants, RAF, SAS, NEPENTHES, Nigel Cabourn, comoli, auralee, M43, M47, M52, M65, jungle fatigue, moleskin jacket, military jacket, French army, French military, euro military, MARTIN MARGIELA, AUBERGE, BONCOURA, linen, ventile, THE REAL McCOY'S, TROPHY CLOTHING, USAF, ARMY, NAVY, alpha, air force, army, navy, BUCO, OUTIL, sus-sous, motorcycle coat, Masaki Suda, ANATOMICA, AIR FORCE, US military, oversized, mock neck
