Uh, I hate to point this out, Ms. Ong, but unless that jacket goes around your face, it’s not going to do much to protect you from smog. The same goes for the dress: cold and flu viruses generally get in through the nose and mouth, not the parts covered by a traditional dress.
It is important to note that the cold\flu garment doesn’t have matching gloves. Besides being dreadfully under-accessorized, many if not most cold and flu germs reach the mouth and nose via the hands.
Point taken. The jacket needs a deep face-covering hood, and the dress requires (at minimum) matching gloves and a veil. Hm, they sound like the ideal clothing for a hygenic bank robbery. 😉
