I bought these to wear wear with boots, and I wanted a heavier tight that wasn't sheer. These are heavier, but the sizing is a bit weird. I'm on the border of size C/D and E/F (5'7 and between 150-155lbs). In my experience, when buying the smaller size tight or hose, there was always a concern about tearing or being too "tight." So I went with the E/F and there is way too much fabric. At least these are complete blackout tights, so it's not very obvious, and I can hide the extra fabric under the boot. I guess Hanes tights run a little longer than other brands. I also felt $15 for tights was a bit expensive, but I don't own very many and wanted to get something that would last.  So far I've worn them twice and they seem comfortable and warm. Just wish they were cheaper or came in a 2-pack at a discount (or something similar).
