This pretty flowing dress is from the 70s. It does have an old cloth tag however I cannot tell what it says. IT fits my size 6 mannequin nicely. There is a hidden zipper partially down the back. Dress is in nice condition except for the very bottom. there are some small holes along the hem and a few spots. Please see last 2 photos. It is so long it drags on the ground unless you are tall.

Detailed measurements:

Bust - 32" unstretched to approx 38" stretched
Waist - 26" unstretched to approx 30" stretched
Hips are open
Body Length - 59" from the top of the strap
