Thank you for viewing. I wore it only once. Actually, I have a gray one of the same item, but I don't remember wearing this one... I'm sorry for being vague. There is a white substance attached to the side, as shown in the last image. I have been storing it with desiccant and anti-mold agents, replacing them periodically, so there are no other problems. The opening is Velcro, so it is adjustable. Thank you. I am very sorry, but I will carefully package and ship it without the box. Thank you again.
