BranditMen's Check Shirt

It says not to clean but obviously it needs to be at some point, so what are peoples suggestions?

Is this shirt ideal for winter (material eg flannel) and would it fit a 6' 4 man or be too small

Advertised at 'brandit ladies check shirt' yet all models are males and the sizing is in mens ?

Has anybody received a shirt with no tag over the left pocket and a different looking label on the shirt?
