Hello! Thank you for choosing AcmeBrands. How may I assist you?
Can you please tell me if the store has any medium Calvin Klein shirts in stock?
I'll be glad to assist you!

Which size are you looking for, please?
Medium
Great! Our Calvin Klein shirts come in a wide variety of sizes. If you check the product page on the website and you don't see your size listed, we are currently out of stock. We restock around the second week of the month, so you may check back again at that time.
Oh, OK.  I will check back then, thank you.
Is there anything more I may help you with today?
That's all, thanks again.
Thank you so much for contacting AcmeBrands customer service. Goodbye!
