If you love the Gunne Sax prairie style then you will love this dress! (BTW- PHOTOS LYING DOWN REPRESENT THE TRUE COLORS- IT IS RED,NOT ORANGE
Its from the 70s, and it may have been a nightgown back the the day, but in todays world, this is an AMAZING Boho Cottagecore style dress. It has no tags but it feels like a very thin flannel. 
It has one small hole towards the bottom in the back that I didn't see until I was taking photos, its so busy its hardly noticeable. Please see last photo.
Its got lace around the cuffs and on the chest, and has an amazing red calico print. 
The bottom 6" is ruffled with a contrasting print like the one on the chest. 
Its a pullover and has 2 buttons in the back that would not close on my mannequin.
Please see measurements. Again, it may have been worn as a nightgown in the 70s, but its very much a dress by todays standards.
Measurements taken lying flat- Shoulders-15" Pit to pit-17" Waist-17" Sleeves-17" Length-40" width across bottom-29" For reference, I'm 5"4' and it falls just below my knees
