Make several evenly spaced slits in that old formal. Sew in some bright colored, wedge shaped panels. Put a piece of trim at the top of each slit. Redo of a formal for a fairy godmother or fairy costume?
Love this idea! WobiSobi: No Sew, CrissCross Back, T-Shirt DIY - says no-sew but I am thinking I could actually re-sew the shoulder seams together to wear over a yoga top or jog bra for going to/from yoga class in summer.
