This dress is very simple and easy to make. If you look closely (ignoring the inside of the sleeve there, ahem), you will see that it is in fact nothing more than a very long t-shirt. All you need to make it is a t-shirt pattern and about 1.5m of a stretch knit, double-stretch for preference. Then you cut out the t-shirt, adding approximately 18-20 inches of length, depending on your height and how long you'd like it to be. I've cut this dress to be just above knee length.
It sits a little differently on me than it does on Doris. The waist and hips are pretty accurately represented here but Doris has a very broad back and small pointy boobs, which is the exact opposite to me. Not that my back is pointy.
