Scrubs...I see the cashiers at my cornet drug store wesrin them seems to be the uniform preferred at this location
Black pants and white shirt, look professional.
Comfortable, professional, light color and suit match the chosen color, but not more than three color on one body.
Look bright and confident!! Prepare yourself by reading or searching more information about general medical terms, if there is a chance that ask by some senior customers. Giving more helpful services to those new comers and new residents who need to settle down in Edmonton. They will feel Safety & Security.
I would wear a suit and blouse.
Mostly something comfortable. I wore a nice shirt, fitted pants, and flats. You just want to look put together, there's no need for a suit.
Formals are preferred.
