Can be worn day to night. Very comfortable material. I’m average size 16 and size 16 was comfortable with a bit of room to spare. Received a compliment on it from a friend whilst I was wearing it. Material tends to twist around rigid v bar in front middle of the jumpsuit during the wash. Easy enough to twist back round each time, but I wonder if it’s something Roman could re-design if making a similar garment in future, as would be good to not have to do that each time.
