The color is navy. It's UV cut, so it's useful in the summer ✨ Size is for children, 140cm. Measured flat: width 41cm, length 53cm. It's a size that adults can wear, but since it's a children's size, the sleeves are short, 3/4 sleeves. You can't wear it outdoors, but it's also recommended for those who exercise at the gym. I've washed it after wearing it 2 or 3 times. There are no noticeable stains, but I cut off the name tag on the inside because I didn't use it. Please refrain from purchasing if you are concerned about this.
