I purchased this on Mercari before. My child's tastes changed at just the wrong time, so I haven't had a chance to wear it at all. I'd like to sell it to someone who is looking for it. There's a faint black mark near the bottom buttons. There's a light brown streak stain on the right sleeve. Since it's a used item, there may be other minor imperfections. Please refrain from purchasing if you are particular about the condition being perfect. It's 100% cotton and made of a soft T-shirt-like fabric.
