Bra tops are my nemesis. Borrowed a fabulous set from a girlfriend (short notice, no time to drive home and pick up my own). Front closure popped at wrong moment, swiftly turned back toward audience. Realize, no quick fix, did a sweeping bow and off stage. (Eeks!)
Second time, dancing at restaurant, long tables of corporate representatives. Thread gave on hooks. Elbows came down so fast bra didn't have time to shift. Graceful bow, exit to ladies room. Fast costume change. Return before next song begins. One lady said, "You're good." Meaning 'no one else at the table noticed what had happened'.
Something is bound to happen..... (keeps a dancer on their toes).
