Always on the hunt for interesting hosiery, I picked up these stay-ups from sockdreams (I swear they don't even give me money, I'm just in love with their selection and prices).
Beautiful sheer beige nylons with slightly raised stripes going down. They have a delicate pattern at the bandings and a bow, if you're into that schoolgirl thing. (I'm not) There's a lot more I could say about how much I love these -- how they actually stay up, how sexy yet elegant they look, etc.
Fit on these is like most thigh highs from this brand, "one size fits most 90-160lbs" but the bonus on this pair is they are available in plus size as well.
