This black cotton interlock comes from Guthrie & Ghani shop in Birmingham. They have a great fabric selection, and although they are quite expensive, it is kid of OK if one saves the shipping costs. We had a gig in the very same street, so I could not go! And I spent too much money there, of course.
The engineering is quite clever. The fronts are cut in the bust dart area and one runs into the other, producing this twisted effect. I simply made it a bit longer, since midi dresses are popular nowadays. Also, I sewed the neck cut higher, which is a pity, because it was gorgeous with the deep cut, but I intended to wear it to school, so...
Well, all in all, it is really nice, comfortable, and becoming, but the skirt gets a little stuck around my legs if I wear it with cotton tights. It would be better with nylon ones, probably, but I do not wear them so often these days...
