Due to the nature of the material, there is a place on the left chest where the thread is raised. It's navy, but it's almost black, so it's not noticeable, but please check the image. I have worn it about 10 times and hand-washed it with Acron each time. ↓ Below is from the official website: Sheer short-sleeved cocoon knit that is cool even in midsummer. The fabric made of crisp yarn has a dry touch and a cool feel. The natural-looking fabric and color, with subtle glitter, create a modest luster and give a sophisticated impression for adults. The material is rayon and polyester, but the texture and feel are like linen. Because it allows air to pass through and has a design that minimizes contact with the skin, you can wear it comfortably even on hot days. This top is light, wrinkle-resistant, and easy to care for at home, making it a great companion for a comfortable summer. It's also great for travel.
