This was custom-made at Tan Loi, a high-end silk shop in Vietnam. The company is particular about raising high-quality silkworms and is highly regarded overseas. I think it cost over 10,000 yen. I've worn it a few times, but the collar's core hasn't lost its shape. It's a one-of-a-kind, completely custom-made item, tailored to my measurements. It's 100% silk, so it feels very smooth against the skin. Also, it's more airy than cotton and doesn't stick to the skin. Because it's breathable, it can prevent stickiness and discomfort even in the sweaty season. Recommended for those with sensitive skin. The fabric has a sheen, and the color appears darker or lighter depending on the light. There is a sister item, "Men's Vietnamese Silk Shirt [Green]". The material is the same, but the color and pattern are different. If you are interested, please take a look. ★Please note that used clothing, or even new items, may have some minor stains due to long-term storage after photography. ★To support SDGs and maintain low prices, recycled materials may be used for packaging.
