This is a travel jacket from THE SHOP TK, the casual line of TAKEO KIKUCHI. As it's a travel jacket (as shown in photos 10 and 11, it comes with a carrying bag), it's lightweight for easy portability. It also has no lining, and the material is 100% polyester, which feels good against the skin, making it perfect for the warmer months. You can easily wear it like a shirt. The design is a classic navy tailored jacket with front pockets. It also has a center vent, and the cuffs have three buttons (functional buttonholes), giving it a proper tailored jacket look. Although there's no lining, as you can see in photos 3 and 4, the seams on the inside and the pocket openings have blue striped piping, which is stylish. The pattern is solid, but as you can see in photo 7, the fabric itself has a check-like texture, so it looks like a check pattern. It's simple, but there's attention to detail in the design. The size is L. Here are the approximate measurements: Length 70cm, Width 51cm, Shoulder width 41cm, Sleeve length 61cm. I wore it a bit, so there's some wear and tear, and there's a scratch near the bottom of the right chest, as shown in the red circle in photo 9. However, it's still perfectly wearable. Jackets worn in the warmer months tend to wear out quickly, so how about this jacket as something you can wear without worrying about it? It's navy, so it's easy to match with anything. Thank you.
