Nancy said that Bruni, in an attempt to look taller than her short hubby Sarkozy, opts for flat shoes, which certainly doesn't look glamorous. She then advised the former Italian model to wear heels as they look more glamorous. "Always wear heels - don't be like Carla Bruni. She has a short man, I see the problem. But if you want to look glamorous, you have to go for heels every time," The Daily Express quoted Nancy, as saying.
