This item can be worn by adults, but it's likely best suited for someone with a slender build, around the size of a child's 140-155cm. It's in good condition as it's hardly been worn, but I wore it a few times initially and there's a slight pull at the armpit, so I'm offering it at a reduced price. It's not very noticeable when worn, but please refrain from purchasing if you are concerned about it.
