have you seen Flies ? they always like to stay on naked things like fruits, naked sweets, naked garbage, but you won't find them on covered bags.. because that covered bag use to protect food to prevent the germs and the flies. Same as the Hijab protects women from the BAD eyes of the people... you want to see her NAKED completely to get the idea of her age ??? that's ridiculous !!! even with that you cannot tell her exact age !! by seeing her face/skin/hands we can easily tell that she must be in the age group of 16-24...
