I wore Khakis or other nice casual pants (preferably with a little spandex woven in... for flex not tightness!) or I wore navy, black, brown, or khaki colored "nice" scrub pants. Something that didn't look too clinical. I did peds and often was at school or in the community with clients so needed a balance between looking discrete (not like a nurse) and easy movement and easy washablity. I had one girl I went to school with where I needed pocket room- pushing her chair, carrying pulse ox, stethoscope, pens, chart form, book for me, etc. We often had little emergencies and had to leave the classroom in a rush so I couldn't be grabbing more than one extra thing so I did wear a scrub top there some days. I'd pick the fashion tops that again, don't look too clinical, since they mirror casual styles. Like the crossover tops in nice prints.
Dark Crocs with no holes in winter (they do so well in snow) and casual flats other times. Nice socks in homes that require you to remove shoes! Slippers in my bag.
Preggers, I wore jumper dresses a lot since I never found pants I loved and I got tired of rearranging them when I stood up, sat down, or played on the floor. Always Crocs with them since my feet were too big for anything else, LOL.
