This garment is unworn, and in very good condition.
It is unsold shop stock from the 1960s or thereabouts.
It still has an old 1970s hand-written shop tag attached.
It has been properly stored, and as you can see, it is in very good condition, with just a few tiny storage spots.
However, in view of its age, it should be hand-washed before use, and treated gently.
