My earlobes were slightly exposed. This size fits comfortably for those with a head circumference of 55cm to 59cm. (The image shows M size being worn) It's a refreshing blue with a hint of green ( ´∀`). Blue colors look beautiful in the pool. Please try it. High-quality fabric with deep color! It's easy to match with any swimsuit and is recommended for those who dislike tight elastic or for men! ◆ We accept returns only if there is a defect in the product.
