The pattern is unusual and the material is perfect for summer! I don't know the brand, but it seems it was purchased a long time ago at a select shop. It's a bit wrinkled because it contains linen, but it's recommended for those who like vintage clothing! My husband wore these often, so there's a sense of use, but I don't think there are any noticeable stains! If you're interested, feel free to comment or purchase. ☺︎ Instant purchase ○
