I do not like the fact that they are sheer all the way to the top of the leg.  I like to have a little less sheer from my thigh up to the top of my leg.  And that is so that my chances of ripping or snagging at the top is less likely.  The waist smoother tummy control otherwise is great.  But because they are sheer to the top of the leg, I will not purchase that type of panyhose again.  Thank you.
