Thank you for shopping with AcmeBrands! How may I help?
I am wanting to buy this shirt but would like to know how big the collar is Product: shirt  Brand: Calvin_Klein  Amount: $94
Let me find out for you! One moment, please.

The most common collar size is 15 inches. We do have smaller ones that are comfortable for 14 inches, and the largest ones are best for 16 inches. Is there anything else I can help you with?
So the larger one would be most likely not to squeeze the neck then>?
Correct! Most people are fine with the standard 15" size, but if you're worried, go for the 16".
Ok,  thats all i needed  thanks
You're welcome! Have a wonderful day.
