I usually buy mine from M&S (no vpl I think they're called) but not only do they show a knicker line, they also bobble terribly after a few washes. I like no vpl especially as I do a lot of sport so wear running tights often. The Uniqlo ones are really good but I tend to save the couple of pairs I have for special occasions, not everyday, which is what I'm looking for.
Does anyone have any recommendations?
