Not to come across rude, folks, but why do you care about lines?
Just curious to hear opinions.
It has to do with the show arena. Panty lines are incredibly noticeable in white and tan breeches or tights. I don't even come from a showing background and it was drilled into me by my instructor not to have them show. It is a huge, big, fat, NO.
As for why I care?
Because I don't need some sicko saying, "Hey girlie, I can see your panties! ..*follow up with some gross pick up line*.." It has happened before, I don't want it happening again. And they show, even in tight jeans you can see them on people, so I buy underwear with the thought in mind of whether or not they will show beneath my skirts, my breeches, my jeans, my tights, etc.
Poor example but, it's like seeing women with large breasts never wearing bra's. You are going to notice. If you don't mind people noticing, fine, that's all on you. I don't want people noticing with me. I am very often on the receiving end of rude comments because I am young and approachable (meaning I'm not scary or angry looking enough to be left alone, like say, my husband is).
