I love the Lanz nitegowns at the VT country store. Too expensive now. I made 2 long (to the floor) flannel nitegowns last winter. Even in SC I wear flannel inthe winter - in the evening, love to sit at nite and have tea or cocoa, read.
I have a pattern I've used since way back in the late 60s - even hubs 1 wore a flannel nightshirt in the WNY winter nites. (looks like a nitegown to me lol - but it has a shirt collar and is cut down the front all the way and buttons like a shirt with a curved shirt tail hem.) I use this pattern now. Very comfortable, very very cozy. sharet
