I've now got 3 pairs of Brilliant Black and I love them as my basic knickers under everything. There's no visible pants line, you can just put them in the washing machine and they are really longlasting. They run very true to size, so even if you're used to size up in other knickers you might want to buy your regular size in WMYP! Since there's no elastics at the seam they don't cut in, just smooth curve hugging goodness
