I agree that anything is better than scrubs. I think dark jeans in appropriate cuts are okay, too. Cleavage is another matter - if your clients are showing it, a little is okay. If they're not, it's not. We are in sales after all and I cannot tell you how many successful middle aged men have advised me to hire "cute young things" to sell eyewear. Turning cute young things into opticians is another matter entirely though, and I'm certainly not advocating hiring on looks.
