Questions: Fashion & Beauty

If you're not into curvy girls than obviously I'm not asking for your opinion.

I believe that we have mostly accepted that leggings can be warn as pants. This is not just because I do it. It's because my friends do it and a lot of women I don't know do it also. Leggings are nearly a part of the soccer moms uniform. They are usually comfortable and never need ironing. My question isn't if they should be worn as pants but rather what should be worn under them. I bring this up because of an interesting conversation I had with a friend and I would like to know which of us is more correct. My belief is that any panty line if visible is still a panty line. It doesn't matter how far up it is. This led me to ponder if it is important at all. Seriously who actually cares if there are lines back there or not? It's not that simple though. I don't wear anything because when I did I wore regular underwear. No thong because I hate those things. The problem I had was worrying how everything looked back there. I knew that one side was higher than the other because my bum tends to munch on undies. I never have to worry about pant lines any more. I do however have to choose leggings much more carefully. My thought is why care about vpl. My question is what do you prefer? I don't know what to expect from this poll but I hope it isn't a thong. I hate those things. LOL
