what's the appeal of tan lines?

I don't like tan lines,yoir body looks ugly..

well tan line are usually noticed in those point of our body where we usually kept hiding in normal way so when body color changed in that particular area it is notice by easily and who saw this started thinking about those part or situation and it became appealing

There are two views on this.
...one is that tan lines are sexy because you can see areas that haven’t been shown in public and therefore lack the tan.
...the other is that a lack of tan lines is sexy because they aren’t afraid to show those areas in public.

What's the appeal of tanning salons

Are you kidding? Don't you think a woman's milky white breasts/nicely-sized areolae look like a couple of savory vanilla ice cream sundaes against a tanned torso?

I don't like Tan lines if i can get away with it.
