Simple and chic vintage 1940's blouse in thick basket weave sky blue cotton fabric.
Cap sleeved top with italian style open collars, bust and waist darts for shape, three aqua green buttons to fasten and nipped tucks at the waist with ties which fasten around the back of the top.
Possibly a home-made example, but very nicely done! Looks great with a classic forties wartime style skirt, chunky perspex jewellery and pin-up shoes ...
