Lest we forget.... this is 2020.  
 
These face masks are comfortable to wear for extended periods, have elastic ear loops, and come in three sizes (for babies, children and adults).  They're well made, fully washable and have a space within the inner lining to insert additional filter sheets (not included -- I hear that HEPA filters for vacuum cleaners, cut to size, are pretty useful). 
 
Keep yourself and others safe from contagion and show consideration --  and show a little bit of UGLY style while you do.
