I'm still in orientation. My hospital had one day of General Hosp Orientation then 3 days of clinical and next week will be 3 days of Nursing Orientation. The only stipulation was that we could not wear jeans or shorts during General Hosp orientation. All other days we can wear scrubs. But there are still the young'uns that seem to think the rules don't apply to them and they showed up in jeans. I was disgusted as I wore very nice business casual as they suggested.
If it's the south where you are, then like here, capris should be fine. Otherwise, I'd go w/ what you suggest but full length khakis instead of capris.
