Doing business is a hard thing to do for any retailer, especially if you have to take measurements. The best advice to help solve these new challenges:
•          Taking precaution with disinfecting spray/gel
•          Washing one’s hands very regularly
•          Working by appointment only and with max 2 persons
•          Do a pre-meet via Zoom/Skype to limit the number of ‘live’ minutes
•          Split shop in two so people don’t cross each other preferably with signs
•          Expanding opening hours to serve more people by splitting shifts
•          Using masks (every three hours a clean one)
•          Using gloves after taking a course on how to fit and undo them
•          Using a pespex screen with holes to reach through
•          Using a good sizing/fitting garment
•          Taking measurements by a roommate/partner
•          Taking measurements with a scanner
