Silk Nightshirt

I am trying to find a silk shirt as Will Truman was on the Season 7 episode 2 of "Will and Grace" It was a long, button-down, striped and silk. It was just a nightgown. Could someone help me try to find this t-shirt, or one similar that I can buy? He want to be buttoned down, and silk ...

trying to express for men, they could have and it wouldnt be too expensive as other stores, especially caustic silk!
