AcmeBrands, how may I help you?
Hi, I just have a quick question about a shirt.  Do you know a lot of the product details?
I can find out for you. What would you like to know?
on the Calvin Klein shirts, do you know if the buttons are brown, or black
Let me find out for you.

The buttons are dark brown.
Okay, that sounds good
Is there anything else you would like to know?
and that was really all I needed.  Thanks for answering
Have a good day.
