My sewing group had heaps of fabric donated and amongst it I found a panel that was four square scarves. I wanted to make a skirt from them, but it would have been very short so I came up with this.

I hemmed each scarf on two sides and then joined them together. I cut off the top corners to fit across the T-shirt. (I'd shortened that a bit.) Stitched the shirt to the top and I now have a dress.
It was very difficult to photograph! The right hand side will give an idea of how it hangs and the left side an idea of the construction.
