I could not find tag, so no idea how old this dress actually is or who made it. it is for sure vintage though! I'm guessing maybe the 70s from the style. It has puffy shoulders on the sleeves which go all the way to the hand with a clasp if you want to wear them like gloves. The train is pretty long, but there is a loop on the inside and a button on the back so it can be put up for dancing. The back is somewhat open with a mesh covering and a bow at the bottom. it's also got a high neck collar.
I am 5'6 and when I originally wore it I was probably 130 lbs? It still fits now and I am 120 lbs, though it is a bit big on the waist. It has a built-in bra (message me if you want to know size, that feels weird to put in description.)
The dress is in good condition, though there is some fraying on the inside. That shouldn't affect the integrity of the dress though.
