TanLines!!!

[violet lightning]

While I also like evenly tanned skin and also creamy light skin, I think tan lines are sexy too. Especially as you said, the long, thin thong ones.
I think they're sexy in part because they "accent" the body, kinda like tattoos, or how stockings accent a nice pair of legs.
To me, its also partly because tan lines used to be found almost exclusively on gg's, so it was hot to see them on a tgirl, because that made me know that they were actually out tanning somewhere in a bikini!
I find them sexy on gg's too....

Duda comes to mind...
