The pattern for this muumuu with shoulder ties was published in 1976. My fabric is a black poplin with purple flowers and green leaves, purchased from Got Fabric a couple of years ago.
As I am larger than the largest size, I enlarged the dress slightly in the front to achieve a half size larger. I need not have bothered as the fit is generous.
The hem allowance is deep - 5cm - and could be reduced if desired. My dress is plenty long enough and could be a tad shorter.
This dress should be fun to wear in really hot weather, and I am pleased with the result.
