Personally, when I see a girl with nude tights, it reminds me of very very young little girls and make me feel like a pedophile for even looking at her. It's like, disgusting, eww.
Then, when I catch a glimpse of her feet, I just think old grandmother. You know how they wear like those really old looking high heels made for old people, with like a thick steel reinforced heel. And to top off the sexiness, an old person sock netting. Yeah... no.
I prefer nude tights for psychological reasons. I like in the UK so it's rarely hot here haha. I always like something on my legs to keep warm as I really feel the cold. So when it's hot, I'm just not used to having nothing on my legs, hence nude tights :) xx
