I bought these before in black and had to get them in white also.
They're excellent shirts.
Unlike other shirts, they collar doesn't seem to stay stretched out after being washed.
The length is approx. 3" longer than other white shirts.  This helps keep them tucked in when you're moving around.
Basically, I'm not going to be wasting money on other brands anymore.
I found what I was needing, when I found these!
