I call this my blanket dress. It is made from a thicker, dark-gray wool and so long an cuddly like a blanket!
Yes, I am one of these, I am always cold. :D
I might have chosen a higher fitting class, so that there is more ease. The bodice is a bit tight when I layer a sweater underneath. But you can change that if you want to sew one of these, too. ;)
I have lined the bodice, but the pattern includes facings for neck and armholes, too.
