I'm looking for some really well fitting knickers. I used to buy M&S, but just not that impressed with them anymore. Happy to pay a bit more, but must fit a size 16 apple shape, high leg, black preferably, mainly cotton. I've tried TU, Nutmeg, Tesco, but none fitted well. I'm wondering if Sloggi are the answer, but seem to remember one of their styles not fitting well - think riding up the crack 😂 Any suggestions?
