This is a lovely vintage, 1980s dress from my own wardrobe

It is made from cotton i believe. The label had been removed when i got it, but apparently it was M&S (also hard to tell the actual size because of no label)

Elasticated waist (at the back)

It was a little large for me, so i would say a 16? I did a temporary adjustment to make it fit me (now carefully unpicked)

Measures 40cm across the waist x 46cm from underarm to underarm x 113cm long

Great condition and a lovely piece.
