if you want to wear white in the "off" seasons i guess you'd say
wear what they call "winter white" or an off white color.
as for nude hose - if you can match it to your kin tone - wear it, nothing bothers me more than someone wearing too much of one damn color or odd hose colors, like purple? who wears purple hose? you don't do that - if your outfit is not a standard color, you go with nude, as long as it shows up nude and not "suntan" color - that bothers me too... lol
