Classic White Polka Dot Dress

Bought this in the UK, from a shop called Phase Eight and brand Damsel in a Dress. Worn it a couple of times but it is in great condition. Vintage look, a line dress with pockets. White buttons down the front. In the winter I have worn it with a white long sleeve bodysuit. It has a small chequered pattern to it. UK size 12 which is a US size 8
