Educated, sophisticated woman (me) needs nightwear

I've been looking for some decent nightwear for ages. When I say nightwear, I mean nightdress. Not PJs (can't be doing with all that ironing) but a pretty, warm nightie that's not pink. I don't want to look like Queen Victoria on a bad reign day, or a member of the B team about to go to work down the Reeperbahn, nor do I want a huge kitten or a teddy or a rabbit on my chest. There must be other women out there who have the same problem. I know Marilyn Monroe used to wear just Chanel No 5 in bed; was that because she couldn't get a warm nightie either?
