Vintage 70s 80s Principals Pink & Purple Tea Dress 10

Vintage 70s or 80s Principals pink and purple tea dress. The size stated on the label is 10 and that is about right. The measurements are: 39cm across the waist, 120cm down the back, 63cm down from the shoulder to the sleeve. The bust measurement is hard to take as the sleeves are batwing style. 100% viscose. Good vintage condition apart from slight looseness at the buttons.
