DOCKERSMen's Classic Fit Long Sleeve Signature Comfort Flex Shirt (Standard and Big & Tall)

Does the black shirt have black buttons?

How can I return this item?

Do these fit like regular Dockers shirt i have a medium in regular fit and want to purchase the same is it safe to do so ?

I like to wear my shirts out, are these the short long tails - like a no tuck shirt?
