This is a Houston Heavy Viera Cotton Shirt. It's a fairly thick cotton shirt, sturdy and durable for long-term wear. The size is M. Made of 100% cotton. It's meticulously crafted with vintage shirt details such as cat-eye buttons, union ticket, and side gussets. There are no noticeable stains or damage. I've only worn it two or three times. How about wearing it under a denim jacket, leather jacket, or Barbour? I am 171cm tall and weigh 63kg. I wore it under denim jackets and leather jackets.
