The Constanța, Romania-born actor also wore weathered white Nike sneakers, and a dark newsboy cap. 

Sebastian wore wayfarer sunshades, and a CDC-recommended standard blue surgical face mask.   

Stan’s considerable facial stubble was still discernible from underneath his face covering.   

His love Alejandra also wore the same type of face mask as well as a white tee, although hers was of a more feminine cut.

She let her blond hair hang long, and donned black leather ankle boots on her feet.
