The dress I was given in Japan is made from floral and stripe cotton, with an empire line band and A-line skirt. I love the V-neck front contrasting with the square neckline at the back. I think the shape is flattering and it is really comfortable.
Although this dress isn’t vintage, I think it can be styled as Twenties and Thirties. Inspiration would be films Paper Moon and O Brother, Where Art Thou? There are lots more out there, and some great original photos online. I’ve collected some on Pinterest.
