Step 1: Dress any way you like
Step 2: Wear Goggles and a N95 mask (properly fit) or KN95
Step 3: Once you don your mask and goggles, you either cannot touch them until you have completed your task or you must properly doff them off and on. This means you must wear gloves, wash hands, never touch your mask or goggle with anything other than clean hands or new gloves and never ever touch the inside of your mask or goggles until you are finished with them for the day
Step 4: You are done with your day. You must remove all your clothing (except for your gloves) for bagging and cleaning; leaving on your gloves, mask and goggles. Remove your mask and goggles and set aside. Remove your gloves and immediately wash your hands then your face and neck. Put on new gloves and either dispose or set for re-use of your mask and sanitize your goggles for re-use. Once everything is put away, remove your gloves and soap and shower your entire body.
With only Mask and Goggles as your actual PPE you have protected yourself to the level of a medical practitioner (also because you doffed properly). Once you understand this concept you are in control of how protected you are at any time you choose.
This means you can fly, be next to anyone and, most importantly,
DO NOT CARE WHAT ANYONE ELSE IS DOING BECAUSE YOU ARE SMART AND PROTECTED
