Who wears heels over 4"?

I love heels and wear 3"-4" heels every day for work and even on weekends I wear them often.
But I'm thinking about getting some that are over 4" (like 5"-6") ...I'm not talking aboout trashy looking ones but high quality fashionable shoes. But I do want to know what people think about an already fairly tall woman wearing 5" heels with a suit at work or jeans on a weekend?
What thoughts?
