Has anyone found really comfortable black opaques that don't pinch at the waist? I have tried M&S, Primark and pretty much all the supermarkets, but they all end up pinching horribly at the waist which is a) uncomfortable and b) looks awful under anything even vaguely fitted. I have taken to buying XL tights (I actually wear M) in the hope that they will be a bit looser, but just end with baggy knees and a pinched waist. I don't have rock hard abs, but I am pear shaped so my waist is relatively small... why does this happen?? I am beginning to lose hope that I will ever find comfortable tights... has anyone found the holy grail?
