I bought this online this month, but the design is too youthful and cute for me, and I haven't had a chance to wear it, so I'm selling it. It's made of a crisp, slightly stiff material that's unlikely to wrinkle. It's a free size, but it's a generous fit, so I think it would be suitable for someone who usually wears a size L to LL in a more structured shirt like a button-down.
