OK, I've put 50's but this dress appears to be brand new. It is hand made and had no buttons which I have put on. It is made in an old fashioned way with hand sewn button holes and little snap bra strap holders (see last pic) so I'm not sure if it has been unused/deadstock and in storage or is made by an old granny or what.
Anyway it is lovely and in perfect condition.
Length shoulder to hem 35"
All measured flat and approximate.
