TIE BELT. This is adorable! Go to a thrift store, find two men's ties with the same width (to make it proportioned for when you cut it) then mark where you want your button to be and with that mark, place it on your belly button and trace the tie to your spine and mark it there. Do the same thing with the next tie and mark it. Once both of them have been marked, cut it and sew both side together and then work on the spot you put the marks for the button to be.
