No NonsenseWomen's Sheer Knee High Value Pack with Comfort Top

What size would fit an 8? By the sizing chart it looks like I could do either?

Do they feel silky?

The title of this product states 10 pair but in the cart, the description states 8 pair. Can someone please verify as of 2-14-20? Thank you!

Would these fit a size 6 foot and the persons weight is in the 180's? Thank you.
