I love 1 for U nightgowns. I have five that I wear for lounging and sleeping.  They wash well, I damp dry and hang them up and have not had bothersome shrinkage or wrinkles.

This model is one of my favorites.  The sleeves are nicely long.  The fit is slim but not snug.  The placket stays closed. Sometimes when sleeping when one button can tug open, but since the buttons stay on. The pockets are a nice bonus.
