Christian Dior-Robe De Chambre?

I have searched EVERYWHERE. Not kidding. I am looking for a robe. My dad has one and it's a little old. It's Burgundy. It's called, "Christian Dior, Robe De Chambre" He LOVES that robe. but, it has so many holes and tears in it he needs a new one. I wanted to get it for him for Valentine's Day. If you could help me I would love it.
