Dress Code for Moonlighting

I would like to ask what dress/outfit you use for moonlighting. Asking for those who are corporate doctors, in OPD clinics, in HD clinics/units and in wards/hospital setting. Do you just go for smart casual, scrubs, white coat or your workplace's uniform? If white coat, is it short-sleeved or the long-sleeved ones?

Many thanks to those who will answer.
