I used to really like Sainsburys shaping tights and would stock up when they had their 25% off. They were firm hold, the waist was high so very smooth silhouette under clothes. They looked like bare legs but much better.
Dear God though. At some point they must have changed manufacturer and now they roll down and I keep having to hitch them up and fight with having a silhouette like links of sausage! 
I had a look in M&S and theirs seem to have stripes down them to 'slim' your legs!
What fresh hell is that?!
Can somebody please help me look reasonable? Nude, firm hold, high waist, no fucking weird stripes and don't ladder in 5 seconds. Is that too much to ask?
