Is this for wearing around the house, or were you planning on flashing people in the supermarket parking lot? Cotton lining.
Velvet exterior.
Belt.
Then comes all the wimmins. (Or so I've heard...)
Back in the 1980s one of my high school friends, a big Aerosmith fan, wanted to look like Steven Tyler. So he went to the mall and picked out an expensive long robe that looked like a kimono. For the next couple weeks he wore the robe everywhere he went, until someone told him, "Hey, dude, what's with the robe? You look like an old housewife wearing a kimono."

I think I found the perfect robe for you.
No need to thank me.
I saw it, and I thought, now that's the robe for Billy.
