The promised tutorial! You can make a top like mine using a tried-and-tested t-shirt pattern as a starting point. It doesn't matter if it has bust darts, you can transfer that width into the excess material for the twist. For this design, you want a top which a good waist shape but isn't skin-tight. Oh, and obviously, this design is only suitable for jersey fabrics. This is what the bodice pieces for a normal t-shirt will look like. As usual, it's much easier to do any pattern alterations…
