Vintage Women's Midi Dress - White - 12

Vintage dress - bought from a vintage fair. Only flaw I could obviously spot is one small thread on inside of collar (last pic) not visible from outside otherwise general wear for being vintage but pretty good in photos! Lack of labels - says GB 18 however as we know vintage sizing is not the same as today! I'm about 10-12 and it fit comfortably with a little room there so could probably fit multiple depending on fit preference. Probably polyester but as you can see it's quite see through on top so I normally wore a vest. Elasticated waist, has belt loops but no belt came with it. Easy to wash and dry and pretty pattern :)
