In order to fight any further diffusion of Covid-19, people are advised to be very cautious when meeting others, even outdoor. A distance of a meter or so must be kept - and a face mask (better if surgical) worn - in case of any personal encounters.
.:. Though Milan and Lombardy are still at risk, some behaviours are allowed. Starting from Monday, April 26 shops are at work, bars and restaurants may serve outdoor (indoor, cautiously, till 6pm), and museums, theaters and cinemas begin to operate again. Shopping malls still closed during the weekends. No evenings with friends: four people max. Curfew 10pm-5am anyway.

from January 7, 2021

Even in a time of pandemic Milan has been no exception: here too January was time for sales. The research (struggle?) of good and cheaper stuff started on the first Thursday of the month, to last nominally till March 7 -- but unofficially much longer. If you're looking forward to a shop-till-you-drop session, remember that changing rope is your right... but keep the receipt!
.:. The best area, and obviously still the most expensive, is Monte Napoleone. In the main shopping areas, such as Corso Vittorio Emanuele and Corso Buenos Aires, temporary shops are increasing. A try may be worthwhile.
