She had begun to walk better in the past few days, but after the tiring wedding, with the heavy train, she started to walk in that clumpy way. I believe that when she's tired she just walks that way to keep balance on those very high heels. If she wore lower heels she would not need to walk this way to retain balance. If a person is going to set up a handicap like a heavy long train, she will compensate in her walking, that is, if she is sensible like Stephanie. I don't like "trains" on dresses, especially heavy long ones.
