Will I look like a fairy if I walk outside with an umbrella?
Not if you move to China, my daughter is there at the moment. She can't buy sunscreen, and everybody walks around with an umbrella.
I have heard, perhaps not totally correct, but Asians believe that fairness (aka, whiteness) correlates with beauty, so especially women walk around with umbrellas on sunny days. Same thing in NYC amongst the Asians.
Plus, being tanned has historically correlated with being a peasant in Asian, so the obsession with no tan, as I understand it.
